Answer:
(B) [tex]\frac{-3}{x}[/tex]
Step-by-step explanation:
A polynomial is the expression which consists of addition, subtraction, multiplication with any variables or constants but the division with a variable is not considered as a polynomial.
Since [tex]\frac{-3}{x}[/tex] consists of division of -3 with a variable, therefore it is not a polynomial, rest all other options are polynomial as they involve addition,multiplication with variables.
