The correct answer is option 1 i.e. Australia

Golden Eagle : Albania :: Blue Crane : South Africa :: Emu : ?

The Golden Eagle is the national bird of Albania.

The Blue Crane is the national bird of South Africa.

Similarly, Emu is the national bird of Australia.

Hence, the correct answer is Australia.

The correct answer is option 2 i.e. BDGJ

V + 2 = X + 2 = Z + 2 = B

B + 2 = D + 3 = G + 3 = J

J + 2 = L + 2 = N + 2 = P

D + 2 = F + 2 = H + 2 = J

Hence, BDGJ is the odd one.

Hence, the correct answer is BDGJ.

The correct answer is option 4 i.e. 6511.

Logic: The last two digits are the product of the first two digits of a number.

1) 4312: 4 × 3 = 12

2) 7963: 7 × 9 = 63

3) 9872: 9 × 8 = 72

4) 6511: 6 × 5 = 30 ≠ 11

Hence, the correct answer is 6511.

The correct answer is option 1 i.e. 2664

Given series: 37, 74, 222, 444, 1332, ?

The logic followed here is as follows: 

37 × 2 = 74

74 × 3 = 222

222 × 2 = 444

444 × 3 = 1332

1332 × 2 = 2664

Hence, the correct answer is 2664.

The correct answer is option 1 i.e. 148.

The logic used here is:

186 - (2 × 3) = 186 - 6 = 180

180 - (3 × 4) = 180 - 12 = 168

168 - (4 × 5) = 168 - 20 = 148

148 - (5 × 6) = 148 - 30 = 118

118 - (6 × 7) = 118 - 42 = 76

Hence, the correct answer is 148.

The correct answer is option 2 i.e. 107

The pattern is as follows: Addition of prime numbers starting from 7.

59 + 7 = 66,

66 + 11 = 77,

77 + 13 = 90,

90 + 17 = 107,

107 + 19 = 126

Hence, the correct answer is 107.

The correct answer is option 2 i.e. BQCM.

The given series: TIUE, VKWG, XMYI, ZOAK, ?

The logic used here is:

T + 2 = V, V + 2 = X, X + 2 = Z, Z + 2 = B

I + 2 = K, K + 2 = M, M + 2 = O, O + 2 = Q

U + 2 = W, W + 2 = Y, Y + 2 = A, A + 2 = C

E + 2 = G, G + 2 = I, I + 2 = K, K + 2 = M

Hence, the correct answer is BQCM.

The correct answer is option 1 i.e. LDS.

Given series: FXM, ASH, VNC, QIX, ?

F - 5 = A, A - 5 = V,  - 5 = Q, Q - 5 = L

X - 5 = S, S - 5 = N, N - 5 = I, I - 5 = D

M - 5 = H, H - 5 = C, C - 5 = X, X - S

Hence, the correct answer is LDS.

The correct answer is option 3 i.e. SHRINE.

The letter 'E' is shifted by one place ahead in each word.

TEMPER, SLEEPER, SIZEABLE, TALLER, SHRINE

Hence, the correct answer is SHRINE.

The correct answer is option 1 i.e. GVTH

AHGF : CJIH :: ETRF : ?

Relation between AHGF : CJIH

A + 2 = C; H + 2 = J; G + 2 = I; F + 2 = H

Similarly,

E + 2 = G; T + 2 = V; R + 2 = T; F + 2 = H

Hence, the correct answer is GVTH.
