Question

Let us define a function g:N⟶N such that g(0)=1,g(1)=0 and
g(x)=x(g(x−1)+g(x−2)) for all x≥2.
Now we define the following sets:
S1= {x∣g(x) is even, x≤5}
S2= {x∣g(x) is odd, x≤5}
T= {x∣g(x) is prime, x≤5}

OPTIONS:
A - Cardinality of s2 is 1
B - g is a surjective function
C - S2 n T is an infinite set
D - Cardinality of S1 is 1
E - The function g is not surjective
