Choose the correct linking verb from the given sentence.
The thief conned money from the old men and grew very rich.
In order find out the linking verb from the sentence, we must understand what linking verbs are. Linking verbs are used to link the subject with it's complement/state or adjective. For example: Roshni is pale. 'Roshni' is the subject and 'pale' defines her state, these two are connected by a linking verb 'is'.
Option A - Conned is not a linking verb, it is an ordinary verb. Conned doesn't link the subject The thief with any complement. Hence, option A is incorrect.
Option B - From is often used as preposition. It is not a verb. It doesn't link the subject The thief with the subject rich in the sentence. Hence, option B is incorrect.
Option C - And is a conjunction, which is used to join two clauses to make a sentence. Here, and doesn't link the subject and the complement, it rather joins the two clauses. Hence, option C is incorrect.
Option D - Grew is an action verb as well as a linking verb. Here, grew links the subject The thief' with the complement very rich. Hence, we can conclude that grew is a linking verb. Thus option D is the correct answer.
