Select the most appropriate option to fill in the blank.

‘Discovery of India’ _______ by Jawaharlal Nehru.

The correct answer is has been written

Key Points

The sentence talks about how 'Discovery of India' is a book written by Jawaharlal Nehru. 

• As can be seen from the apostrophes before and after 'Discovery of India', it can be deduced that it is the title or name of something. 
• The use of the preposition 'by' before 'Jawaharlal Nehru' implies that he is the agent carrying out the action in the sentence.
• Since there is only one title, it can be assumed that the item is singular. 
• This means that the verb in the blank should also be singular. 
• Thus, options  1 and 4 are eliminated because they have a plural verb 'have'. 
• Option 2 is incorrect because the absence of the verb 'been' implies that 'Jawaharlal Nehru' is something that has been written by 'Discovery of India', and this not true. ( we need the passive form)

Hint

• The knowledge that 'Discovery of India' is a single book written by Jawaharlal Nehru would help the reader eliminate options implying a plural noun. 

Thus, the correct answer is option 3.
