In the following question, out of the four alternatives, select the alternative which will improve the bracketed part of the sentence. In case no improvement is needed, select "no improvement". The Congress and JD(S) (will formed a) pre-poll alliance to contest the 2019 Lok Sabha elections, Congress MP KC Venugopal said on Friday.?

Option 3 : will form a

The correct answer is option 3, i.e. will form a.

In the bracketed part, ‘will formed a’ is grammatically incorrect and must be replaced with ‘will form a’. the action has to be done in future thus, ‘will’ should be used and with ‘will’ ‘form’ must be used. Moreover, the given statement is not a compulsion so ‘must form a’ cannot be used. Thus, the most appropriate answer choice is option 3.

Hence, the sentence can be correctly rewritten as, The Congress and JD(S) will form a pre-poll alliance to contest the 2019 Lok Sabha elections, Congress MP KC Venugopal said on Friday.
