Oct 11 at 10:38 comment added rus9384 Asking if the amount of solutions is odd is a problem in $\oplus\mathsf P$, which is not known to be either a subset or a superset of $\mathsf{NP}$. To make it belong to $\mathsf{NP}$, you have to ask if there is at least $1$ (or $k$ that is a number polynomial in $n$) solution.
