If FHB = 36644, then DAG will be equal to:

Correct option is C

Analyzing FHB = 36644
F is the 6th letter of the alphabet, square of 6 = 36.
H is the 8th letter of the alphabet, square of 8 = 64.
B is the 2nd letter of the alphabet, square of 2 = 4.
Thus, the code of FHB is 36644
D is the 4th letter of the alphabet, square of 4 = 16.
A is the 1st letter of the alphabet, square of 1 = 1.
G is the 7th letter of the alphabet, square of 7 = 49.
Putting these together gives us DAG = 16149.
Conclusion: Therefore, DAG will be coded as: (c) 16149.
