A constant horizontal force F is applied to a block Y. Block Y is in contact with a separate block X.

The blocks remain in contact as they accelerate along a horizontal frictionless surface. Y has a greater mass than X. Air resistance is negligible.

Which statement is correct?

A. The force F is equal to the product of the mass of Y and the acceleration of Y.

B. The force that Y exerts on X is less than F.

C. The force that Y exerts on X is less than the force that X exerts on Y.

D. The force that Y exerts on X is equal to F.
