The correct answer is option 4 i.e GBVTKUB

APPLE : CTVTO 

A + 2 = C, P + 4 = T, P + 6 = V, L + 8 = T, E + 10 = O

Similarly for EXPLAIN, 

E + 2 = G, X + 4 = B, P + 6 = V, L + 8 = T, A + 10 = K, I + 12 = U, N + 14 = B

Hence, the correct answer is GBVTKUB.

The correct answer is option 2 i.e. 8.

So, the code of Teacher = 8
