Answer:
B. and
Step-by-step explanation:
The expression given is:
Like terms are terms in which their variables and the power of the variables (exponents) are the same.
While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.
In that case, the like terms in the expression given are and
.
Note: The question says but the option has
