Solution:

Observing the number in the first block we get the pattern as,

(7)2 – 25 = 24

And, 2 * 24 = 48

Similarly, observing the number in the second block we get the pattern as,

(9)2 – 49 = 32

And, 2 * 32 = 64

Therefore, considering the third block we get,

(13)2 – 121 = 169 – 121 = 48

So,

? = 2 * 48 = 96

Hence, (B) is the correct answer.
