Question

point out the specific noun in this sentence. smoking is injurious to health​

Answer 1

Gerunds are words that are formed with verbs but act as nouns. Gerunds also at times are seen to end in 'ing'. In this particular sentence, the word should act as a noun thus becoming the subject of the sentence and as a verb by taking up the object. This means that in the blank, we would need a gerund.

Option A: Smoking is a gerund as it behaves as a noun as well as a verb in the sentence

Option B and Option D: Smoke is the present tense of the particular verb. It does not act as a noun

Options C: Although it ends with "-ing", it does not act as a noun.

Option A is correct

Answer 2

tne answer is "injurious"
