Let PQRS be quadrilateral. Two circle 01 and 02 are inscribed in triangles PQR and PSR respectively. Circle 01 touches PR at M and circle 02 touches PR at N. Find the length of MN. I. A Circle is inscribed in the quadrilateral PQRS. II. The radii of the circles 01 and 02 are 5 and 6 units respectively.

• Statement I alone is sufficient to answer the question.
• Statement II alone is sufficient to answer the question.
• Statement I and Statement II together are sufficient, but neither of the two alone is sufficient to answer the question.
• Either Statement I or Statement I alone is sufficient to answer the question.
