Answers :

1) Answer: B

The original sentence is incorrect.

Reason: There are two errors in the bold phrase.

1^st. Instead of ‘these’ pronoun ‘this’ should be used here.

2^nd. In the sentence, the writer refers to the subject ‘denial’. Therefore, ‘denial’ should be replaced by ‘denying’ to make it a meaningful sentence.

Therefore, among the given choices option B replaces the bold part most appropriately.

The sentence after replacement becomes:

MobiKwik has faced growing criticism this week for denying a leakmany customers and digital rights activists say is linked to the company's database.

Therefore, option B is the correct answer choice to this question.

2) Answer: E

The original sentence is absolutely correct and needs no correction.

Therefore, option E or B is the correct answer choice to this question.

3) Answer: D

The original sentence is incorrect.
Reason: 

1^st. As we can observe that the sentence is made in past tense, usage of present form ‘lapse’ is erroneous here. Instead of ‘lapse’, ‘lapses’ (because the subject is plural) should be used here.

2^nd. ‘is found’ means ‘past and past participle of find’ and the word doesn’t make any sense in the context of the sentence. Instead ‘are found’ which means ‘where it is expected/supposed’ should be used here.

Therefore, among the given choices option D replaces the bold part most appropriately.

The sentence after replacement becomes:

Warned the company it will face fines, if lapses are found a source with direct knowledge of the situation told Reuters.
Option D is hence the correct answer.

4) Answer: C

The original sentence is incorrect.

Reason:

1^st. The word ‘criticism’ and not ‘critics’ is used to denote`the act of expressing disapproval’. Therefore, ‘critics’ must be replaced by ‘criticism’ here.

2^nd. As the verb ‘had faced’ is used in its past participleform, it’s clear that the subject has to be the same. Therefore, the verb ‘had faced’ must be replaced by ‘has faced’ in singular form here.

Therefore, among the given choices option C replaces the bold part most appropriately.

The sentence after replacement becomes:

MobiKwik, which is backed by Sequoia Capital and India's Bajaj Finance, has faced growing criticism this week for denying a leak.

Option C is hence the correct answer.

5) Answer: C

The original sentence is erroneous.
Reason: The sentence implies a contradiction of thoughts and therefore usage of 'towards’ as a preposition is absurd here. Instead, that implies the same context `to’ should be used.

Among the given choices, only option C replaces the given bold part most appropriately.

The sentence after replacement becomes:

The RBI has given MobiKwik an ultimatum and ordered them to retainan external auditor to conduct a forensic audit.

Option C is hence the correct answer.
