The product of a monomial and a binomial is a

⇒ Monomial has single term while binomial has two terms.

⇒ Let us suppose a monomial = c and a binomial = (a – b)

⇒ product of ‘c’ and (a – b) are as follows:

⇒ c× (a – b)

= c× a – c× b

= (ca – cb) (This is a binomial)

⇒ Thus we can conclude that product of a monomial and a binomial is binomial.

Option (a) does not match to our solution.

Option (b) does match to our solution.

Option (c) does not match to our solution.

Option (d) does not match to our solution.

So, option (b) is correct answer.
