Solution

The correct options are
A Gravitational force
D Frictional force

Gravitational force acts downwards due to Earth's gravity. The force opposing his relative motion along the inclined road is called frictional force. Friction is a contact force. Therefore, he needs to overcome gravitational force and frictional force.
