The correct option is C Binomial
A monomial is a polynomial, which has only one term.
For example: xy
A binomial is a polynomial, which has two terms.
For example: x + y
If we multiply monomial with binomial, then we get a binomial.
For example:
xy(x+y)=xy×x+xy×y
=x2y+xy2
Hence, the correct answer is option (c).
