Question

Identify the verb and say whether it is a Gerund or Present Participle:
Start doing the exercise now.

• A. start - present participle
  
• B. start - gerund
  
• C. doing - present participle
  
• D. doing - gerund
  

Answer 1

The correct option is D doing - gerund

A verb form which functions as a noun, ending in -ing is a Gerund. On the other hand, the form of a verb, ending in -ing English, which is used in forming continuous tenses is a present participle.

The two options, A and B are wrong because they do not end in -ing

Now option C is given as present participle. The verb over here is not used as a continuous tense which makes it the wrong option.

Option D is correct because "doing" is a verb in this sentence, which functions as a noun.

Option D is the correct option.
