Question

Replace the underlined noun with the appropriate verb in the below sentence:
Mr. John has made a heavy investment in our business.

• A. Mr. John has made a heavy investing in our business.
• B. Mr. John has made a heavy investigation in our business.
• C. Mr. John has invested heavily in our business.
• D. Mr. John has heavily investing in our business.

Answer 1

The correct option is C Mr. John has invested heavily in our business.

The word, 'investment' is a noun, whose verb form is 'invest'. Its past tense is 'invested', which means: Spent a lot of money to buy something which is likely to be profitable in future. The sentence, 'Mr. John has invested heavily in our business' as mentioned in option C is grammatically correct.

Option A: Here, the continuous present tense form of the verb i.e. 'investing' has been used. However, it is used in the place of a noun. Hence, this is grammatically incorrect.

Option B: The word, 'investigation' is a noun which refers to the process of conducting a systematic inquiry to examine facts and establish a truth. It is not a verb. Hence, this option is incorrect.

Option D: The words, 'has heavily investing' is grammatically incorrect. The auxiliary verb, 'has' is to be used along with the participle form i.e 'invested'; Example: 'has heavily invested'. It cannot be used with the present continuous form i.e 'investing'. Hence, this option is incorrect.
