Given:

The number =  96 × 124 × 77 

Calculation:

We have,

96 × 124 × 77 

⇒ (32)6 × (2 × 2 × 3)4 × 77 

⇒ 312 × 24 × 24 × 34 × 77

⇒ 28 × 316 × 77

Now , we have three prime factors of the given value in the question , 2,3 and 7

So, sum of prime factors = 2 + 3 + 7 = 12

Hence, The correct answer is '12'.
