Choose the correct meaning of ‘look after’ from the options given below–

'Look after' means to take care of someone or something, to attend to or protect. So 'to take care' (B) is correct. A sentence like 'She looks after her younger brother' means she takes care of him.

• A) To look like is wrong. That meaning belongs to 'look like', which means to resemble, as in 'He looks like his father'. It is a different phrase.
• C) To enquire is wrong. The phrasal verb for enquiry is 'look into', meaning to investigate, as in 'The committee will look into the complaint'.
• D) None of the above is wrong because B is correct.

Core concept: phrasal verbs, where the meaning of the verb plus particle is not the sum of its parts. Look plus after gives care, look plus into gives investigation, and look plus up gives search. In Mains, precise vocabulary matters in essay and precis writing, because a wrong phrasal verb changes the meaning of a sentence.

Trap: Students pick A because 'look' appears in the option, but the particle changes the meaning entirely. Learn phrasal verbs as whole units, not word by word.
