Hint: Linking verb is an equating verb that links the subject with the complement of a sentence. For example- ‘be’ or ‘become’.

Complete answer:
In the given question, we have to choose the correct linking verb. The student should remember that a linking verb links the subject with a complement, adjective, or state.
The subject in the given sentence is ‘the thief’.
Let us thus analyze the options given to us in this question:
Option (a.), 'conned', refers to the verb ‘con’.
Therefore, option (a.) is thus incorrect as it is not a linking verb since it does not link any complement to the subject in the sentence.

Option (b.), ‘from', refers to a preposition which means- With the source or provenance of or at.
Therefore, option (b.) is incorrect as it is not a linking verb.

Option (c.), ‘and', refers to conjunction.
Therefore, option (c.) is incorrect as it is also not a linking verb.

Option (d.), ‘grew', refers to the past tense form of the verb ‘grew’.
Therefore, option (d.) is correct as it links ‘the thief’ (subject) with ‘very rich’ (complement).

Note:
In this question, it would be helpful for the student to recall the concept of a compliment. A compliment is a word or phrase used to complete a grammatical construction.
