Here we need to know the current age of Stanley then we can calculate the weight as every year he gains 8 pounds from 18 years onwards only if weight known on 18th year.

Stat 1: Insufficient : We are not sure of the 18th year weigth and the current age..

Stat 2: His current age is 36.. 18*8 = 144 pounds gain from 18th year onwards..Sufficient..

IMO B is correct option..

OA please..will correct if I missed anything...
