Know the rule of COMMA + FANBOYS:
COMMA + FANBOYS: is used in the following cases:
1. Clause + COMMA + FANBOYS + Clause.
Example:
They were playing football, but I was doing my work.
We are taking our breakfast, and they are taking their lunch.
2. In case of list of more than two items,
COMMA + FANBOYS + The last item.
Example:
I have bought X, Y, and Z.
They have done the work, won the prize, and gone to the national festivals.
Now, look at the sentence:
Before
"COMMA + BUT", there is a clause; therefore, we should follow the rule no.1.
==> We should look at the option that has
"BUT + CLAUSE".
MIND: A clause MUST have a subject and Verb.
A - but augmenting
==> We need a subject and a verb. augmenting is not a verb; it is a a gerund.
B - and had augmented
=> It has a verb "
had augmented", but it does not have a subject. So, it is NOT a clause.
C - but he augmented
==> Is has a subject and a verb.
D - and even though he augmented
=> "
and + even though" has made it subordinate. We need an independent clause after BUT.
E - but with augmentation of
==> There is no subject and verb.
Answer: C
