The correct option is
C These are not like terms.
In the terms 4x2y and 3xy2, unknown variables are the same.
- The exponent of x in the 1st term is 2 whereas in the 2nd term exponent of the same variable is 1. So, these are not like terms.
- Further, the exponent of y in the 1st and 2nd terms are 1 and 2 respectively. As they are not the same, these terms are not like terms.
