In the following sentence, a part of the sentence is underlined. Below are given alternatives to the underlined part, which may improve the sentence. Choose the correct alternative. In case no improvement is needed, choose the option ‘No improvement’. Perceptions about the organisation might have been very different has it not whipped up hysteria and intolerance against the media and created an impression of unofficial censorship. Correct Answer Had it not

The sentence uses the form has it not, which is incorrect and needs improvement.

The context of the sentence suggests that the underlined part acts as negative conjunction for the sentences.

'Had', when used at the beginning of a sentence, indicates use as a conjunction, similar to 'if'.

e.g. Had I not met him, I would have remained a loner.

The only alternative that improves the sentence is had it not.

Notice here that 'had it not' is used to mean 'if it had not', both of which are correct. 

None of the other alternatives can make the sentence meaningful.

Therefore, the correct answer is option 3. The correct sentence will be: Perceptions about the organisation might have been very different had it not whipped up hysteria and intolerance against the media and created an impression of unofficial censorship.
