Answer 2

Answer:

Option C

Step-by-step explanation:

We have to find the pair of terms composed of like terms.

(A) 2a, 2b  Unlike terms

(B) -3x, +3y Unlike terms

(C) abc, cab

    As we know cumulative property of multiplication shows a×(b×c) = (a×b)c

    Therefore, both the terms abc and cab are similar.

(D) 4mn, 3my Unlike terms

Option C is the answer.
