Answer : C
A. (5 + 3) × 2 = 16
Here we have 5 +3 . there is a + sign in between. so it does not comes under Associative property of multiplication
B. 5 × (3 + 2) = 25
We have 3 + 2 . there is a + sign in between. so it does not comes under Associative property of multiplication
C. 5 × (3 × 2) = 30
we have 5 times 3 times 2. so it comes under Associative property of multiplication
D. 2 + (4 × 7) = 30
We have 2 + . there is a + sign in between. so it does not comes under Associative property of multiplication
