Two masses, M and m, are connected by an inextensible string which passes over a frictionless pulley. Mass M rests on a frictionless slope, as shown. The slope is at an angle θ to the horizontal. The two masses are initially held stationary and then released. Mass M accelerates down the slope. Which expression must be correct?

1. Asinθ < m/M
2. Bcosθ < m/M
3. Csinθ > m/M
4. Dcosθ > m/M
