2B, 4D, 7G, 12L, 19S, 30D, 43Q, ?

A.

60H

B.

C.

D.

63X

Correct option is A

Given2B, 4D, 7G, 12L, 19S, 30D, 43Q, ?
Logic: Letters are increasing prime number and difference between the number is prime numbers.
4 - 2 = 2, 7 - 4 = 3, 12 - 7 = 5, 19 - 12 = 7, 30 - 19 = 11, 43 - 30 = 13
The next prime number is 17
So, 43 + 17 = 60
B → D (+2), D → G (+3), G → L (+5), L → S (+7), S → D (+11), D → Q (+13)
The next letter should be:
Q + 17 = H
The next series is 60H.
Thus, correct option is (a).
