Answer should be D.

Statement 1: x is a positive interger. Meaning X > 0 and is an Integer.

Now, \((6)^P\) (where P is a positive Integer) will always give the last digit as 6 and hence remainder will always remain 6. --> SUFFICIENT

Statement 2: This is just a filtered part of Statement 1. Meaning in Statement 1, I already said we will get a single solution for X > 0 and X as an integer. Now, this includes both even and Odd. This, Statement 2 is also sufficient.

Hence, D.

Yeah true. My bad.
I jumped to the conclusion after reading statement 1.
