(1) \(x^4\) is even, where x is prime number
Only possibility is x=2, but nothing about y
Insuff

(2) \(x^y\)is odd
We cannot find unique value of any of the variable
Insuff

Combined..
\(2^y\) is odd..
But base is 2, so the term should be even except when y=0 as \(2^0=1\).
Thus x=2 and y=0.
Suff

by non -ve integers , we consider 0 also
#1
\(x^4\) is even, where x is prime number
x=2 ; y not know insufficient
#2
\(x^y\)is odd[/quote]
x has to be odd or 1 ; insufficeint
from 1 & 2
x=2 and y=0 sufficient
IMO C

st1: clearly tells that x has to be even, but x is prime. Only option x= 2; but it tell nothing about y
st2: tells nothing about x and y
combining both yields y to be 1. therefore x= 2 and y = 1
Opt. C
