The word "since" can be a conjunction (of reason or of time), a preposition or an adverb. "Since it was raining heavily, we stayed at home": "since" introduces a clause, but it means "because", so it is a conjunction of reason. "She has lived in this town since 2015": "since" is followed by a noun phrase (a point in time), so it is a preposition. "They moved away, and I haven't seen them since": "since" stands alone at the end and means "from that time until now", so it is an adverb. "It is two years since we last met": "since" introduces a clause and marks the time from which the two years are counted, so it is a conjunction of time. The correct answer is "It is two years since we last met."
