@Rumpel...
1) whats wrong with A. How is "undeniable" different from "cannot be denied".
2) I'm not sure of any plausible explanation for this.
3) can "or" be used independently without using "either" ?

By Eulers theorem 3^4 mod 5 = 1 .
so 3^8n mod 5 = 1
3^(8n+3) + 2 mod 5 = 3^8n mod5 * 27 mod5 + 2 mod5
= 1*2 + 2 = 4
