    I'm not very familiar with this, but I'd say C, since any polynomial should have only non-negative powers. A monomial is a special polynomial, hence the non-negative powers should also apply. Therefore, because this contains y^-2, I'd say C.

    monomial is a single term expression without any addition or subtration operation its definitely a monomial expression no doubt

    I'd say it's a rational function.

    A monomial is a product of positive integer powers of a fixed set of variables (possibly) together with a coefficient

    according to that definition, it is certainly not a monomial.

    It's not a monomial, since not all the exponents of the variables in the expression are positive integers.
