biting / doing

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 in the blank acts a noun thus becoming the subject of the sentence and also like a verb by taking up the object. This means that in the blank, we would need a gerund.

Bite and do are in the present tense.

Biting and Doing are gerunds as they play a dual role

Option C is correct
