True. The canonical projection of a quotient set is a continuous surjection. Its image is compact by the continuous image of a compact space theorem.
For connectedness, if formed a separation of a topological space of , then the preimages would be disjoint nonempty open sets covering , contradicting its connectedness. This proves the continuous image of a connected space theorem in this case. Hence the quotient space is both compact and connected.
