Explanation:

The original sentence is erroneous.

Reason: Usage of the phrasal verb 'look away' which means ‘avert one's gaze' is inappropriate in this sentence.

'Look down on' which means ‘to consider someone or something lesser or inferior in some way’ would be suitable in this context.

E.g.: She looks down on anyone who hasn’t had a university education.

Hence ‘look down on’ should be used in place of ‘look away on’ to make the sentence grammatically and contextually correct.

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

The sentence after replacement becomes:

Religious bigots look down upon anyone who does not conform to their beliefs

Option B is hence the correct answer.
