Answer: 2,3,4,-5

Explanation:

it seems that 40 is supposed to be 4c.

the terms can be grouped in several ways

2a, -5a                   Contain factor ‘a’

8, -4.                Simple integers/constants

2a, 4c,  8, -4.          Even numbers

2a, 3b, 4c,  -5a       Contain a factor      

Can’t group on + or - because values of a,b,c are unknown

From the available choices, only 2,3,4,-5 matches a logical group.
