Like terms means terms that have the same variable (and with the same exponent).  A) 9x and 9y <-- those are different variables. This is incorrect. B) 12ac^2 and ac^2 <-- those are the same variables and same exponent. Correct. C) 8xy and 8xz <-- different variables, incorrect. D) ab^2 and x^2y <-- different variables, incorrect. Correct answer is [latex]\fbox {B)}[/latex]

Like terms are terms that have the same variables and also have the same exponents on those variables. Out of all your choices, answer choice B) 12ac^2 and ac^2 fits that definition. B is your answer.
