Case I :
let us assume n as 2.
n cube plus 2n square minus 5n minus 6
8+8-10-6
16-16=0, which is divisible by 2.
Case II :
let us assume n as 3.
3 cube + 2(3)square - 5*3-6
27+18-15-6
45-21= 24.
so, we get that it is divisible by 2.
hence it is applicable for all.
so (1)2 is the correct opt.
hope this helps you dear....
