The verbs 'enjoy', 'avoid', 'miss', 'postpone', are not followed by the to-infinitive. They should be used with the gerund. So, 'to disturb' makes the sentence incorrect. This is rectified in option d). Hence, (d) is the correct answer.
Since 'Taran' is a singular subject, it will be followed by the singular verb. So, options (a) and (c) are negated. Option (b) also gets negated because no helping verb is present before the present participle form of the verb.
Gerund: Gerund is a verb form that functions as a noun, ending in -ing. A gerund can be either the subject or the object of a sentence.
