Question

Fill in the blank with the most appropriate preposition.

The patients in the hospital are looked after ______ the nurses.

• A. by
• B. at
• C. to
• D. into

Answer 1

The correct option is A by

Preposition is a word which is used to link nouns, pronouns or phrases to other words in a sentence. A preposition is generally placed directly before nouns / pronouns and convey the position / relationship among the nouns in a sentence.

Option A - 'by' is used to indicate the doer of the action, or to express nearness. In the given sentence, the action 'looked after' is being done by the 'nurses'. Therefore, the correct option to complete the given sentence is : Option A - by.

Whereas other options are unsuitable here because Option B - 'at' is used to indicate position or timing, Option C - 'to' is used to indicate relationship or movement of something or direction of something,Option D - 'into' is used to indicate movement of something from one place to another.

The completed sentence, thus, becomes : The patients in the hospital are looked after by the nurses.
