We have to find out the linking verb from the given sentence. In order to find out the linking verb, we must understand it's meaning and usage. Linking verbs are used to link the subject with it's complement/state or adjective. For example: Roshni is pale. 'Roshni' is the subject and 'pale' defines her state, these two are connected by a linking verb 'is'.
Option A - 'And' is a conjunction and not a verb. Here, 'and' is used to join three subjects. Hence, option A is incorrect.
Option B - 'To' is used as an infinitive here. 'To go' can also be replaced by 'going'. The second 'to' is used as a preposition of place. Hence, option B is incorrect.
Option D - 'Go' is an ordinary verb and it doesn't combine the subjects with their state of being. Hence, option D is incorrect.
Option C - 'Are' is a linking verb that connects/links the subjects with their state of being. 'Jack, Jason and Jenny are happy' explains us that the subjects 'are' happy. Hence, option C is the correct answer.
