Answer:
After.
Explanation:
A conjunction is a word that acts as the glue to join two or more sentences or clauses together. It acts as the connecting tool for sentences that are to be joined.
Most commonly, conjunctions are located in the middle of the two sentences that are joined. But sometimes, they can also act as the starter of the sentence, depending on the sentence structure. "After" as a conjunction is used to join two clauses that are independent.
Thus, the conjunction in the sentence is "after".
