Question

Fill in the blank with the most suitable option:
My friend leads _______ a very easy life.

• A. with
• B. in
• C. no preposition
  
• D. to

Answer 1

Answer: (C)

no preposition

Prepositions are words that express a relation (like place, time) between the noun and the rest of the sentence. Usually, the preposition follows an intransitive verb (a verb that does not require an object). In most cases, the transitive verb (verb that takes an object) does not require a preposition.
In the given sentence, the verb 'leads' is transitive, because it is followed by an object "a very easy life". Hence, we do not require a preposition in this sentence.
So, option C is correct.
'With' means 'accompanied by', 'in' means 'enclosed within something' and 'to' expresses an action towards something. These words are not required here as the verb 'leads' is transitive.
Hence options A, B and D are incorrect.
