Detailed Solution

In this question, firstly, we have to combine like terms and then add the terms in LHS and check whether it is equal to RHS or not.
Required expressions:
=8a – 6ab + 5b + (- 6a – a b – 8b) + (- 4a + 2a b + 3b)  = (8a – 6a – 4a) + (- 6ab – ab + 2ab) + (5b – 8b + 3b)
= - 2a + (- 5ab) + (0b)
 =  −2a−5ab   = RHS
Hence, the given statement is true and the correct option is 1.
