Choose the alternative that best replaces the question mark(?) in the given figure.

Correct option is C

In the given series we have 5+3+2 =10,5×3×2 =30-10 =20
Similarly for the next triangle we have 8+5+1 =14 ,8×1 ×5=40,40-14=26
So, for the last one we would have 9+3+2=14,9×3×2 =54 ,54-14 =40
40 will be right choice.
