△LMN\triangle LMN is right-angled at MM and △PQR\triangle PQR is right-angled at QQ. If hypotenuse LN=PRLN = PR, which one of the following additional equalities is sufficient to conclude that △LMN≅△PQR\triangle LMN \cong \triangle PQR? (a) ∠L=∠P\angle L = \angle P (b) MN=QRMN = QR (c) LN=PQLN = PQ (d) LM=PQLM = PQ
