As,

Similarly,

Hence, option D is the correct answer.

As,

Similarly,

Hence, option C is the correct answer.

The logic here is that the place values of all the letters increase by +1 and the middle letter increases by +2 –

C (3) + 1 = 4

L (12) + 1 = 13

O (15) + 2 = 17

C (3) + 1 = 4

K (11) + 1 = 12

CLOCK = 4-13-17-4-12

Similarly,

P (16) + 1 = 17

H (8) + 1 = 9

O (15) + 2 = 17

N (14) + 1 = 15

E (5) + 1 = 6

PHONE = 17-9-17-15-6

Hence, option C is the correct answer.

As,

APPRECIATE is written in reverse order => ETAICERPPA

Similarly,

FRIENDSHIP is written in reverse order => PIHSDNEIRF

Hence, option A is the correct answer.

The logic here is that the sum of the reverse place values of the letters becomes the numerator and the number of letters becomes the denominator of the coded number –

V Reverse 5

A Reverse 26

C Reverse 24

C Reverse 24

I Reverse 18

N Reverse 13

E Reverse 22

5 + 26 + 24 + 24 + 18 + 13 + 22 = 132

Number of letters = 7

VACCINE = 132/7

M Reverse 14

A Reverse 26

S Reverse 8

K Reverse 16

S Reverse 8

14 + 26 + 8 + 16 + 8 = 72

Number of letters = 5

MASKS = 72/5

Similarly,

S Reverse 8

A Reverse 26

N Reverse 13

I Reverse 18

T Reverse 7

I Reverse 18

Z Reverse 1

E Reverse 22

8 + 26 + 13 + 18 + 7 + 18 + 1 = 113

Number of letters = 8

SANITIZE = 113/8

Hence, option A is the correct answer.

The logic here is that the reverse place value of the letters is doubled –

P (11) × 2 = 22

R (9) × 2 = 18

O (12) × 2 = 24

J (17) × 2 = 34

E (22) × 2 = 44

C (24) × 2 = 48

T (7) × 2 = 14

And,

T (7) × 2 = 14

H (19) × 2 = 38

U (6) × 2 = 12

N (13) × 2 = 26

D (23) × 2 = 46

E (22) × 2 = 44

R (9) × 2 = 18

Similarly,

S (8) × 2 = 16

P (11) × 2 = 22

A (26) × 2 = 52

R (9) × 2 = 18

K (16) × 2 = 32

L (15) × 2 = 30

I (18) × 2 = 36

N (13) × 2 = 26

G (20) × 2 = 40

Hence, option C is the correct answer.

As,

P – 1 = O

I + 1 = J

N – 1 = M

K + 1 = L

Y – 1 = X

S + 1 = T

Similarly,

G – 1 = F

A + 1 = B

M – 1 = L

P + 1 = Q

S – 1 = R

T + 1 = U

Hence, option B is the correct answer.

The coding here is done based on a pattern of movement.

C (1) O (2) M (3) M (4) U (5) N (6) I (7) T (8) Y (9)

The pattern of movement is 978564123, i.e. YITUNMCOM

A (1) U (2) T (3) H (4) O (5) R (6) I (7) T (8) Y (9)

The pattern of movement is 978564123, i.e. YITORHAUT

Similarly,

I (1) S (2) O (3) L (4) A (5) T (6) I (7) O (8) N (9)

The pattern of movement is 978564123, i.e. NIOATLISO

Hence, option C is the correct answer.

P + 1 = Q

U – 1 = T

L + 1 = M

S – 1 = R

E + 1 = F

And

HEART is codded as = IDBQU

Similarly

L + 1 = M

I – 1 = H

V + 1 = W

E – 1 = D

R + 1 = S

Hence, option B is the correct answer.

as,

TEACHER= T(20)E(5)A(1)C(3)H(8)E(5)R(18)

= T(2+0)E(5)A(1)C(3)H(8)E(5)R(1+8)

= T(2)E(5)A(1)C(3)H(8)E(5)R(9) =2513859

and

PRESS= P(16)R(18)E(5)S(19)S(19)

= P(1+6)R(1+8)E(5)S(1+9)S(1+9)

= P(7)R(9)E(5)S(10)S(10) =7951010

similarly,

ZYGOTES= Z(26)Y(25)G(7)O(15)T(20)E(5)S(19)

= Z(2+6)Y(2+5)G(7)O(1+5)T(2+0)E(5)S(1+9)

= Z(8)Y(7)G(7)O(6)T(2)E(5)S(10) =87762510

Hence, option D is the correct answer.
