$(a)$. To draw water from the well, we have to $\underline{pull}$ the rope.

Explanation: 

The rope is moved toward us when the water is drawn from the well. So, it is a kind of pull force.


$(b)$. A charged body $\underline{attracts}$ an uncharged body towards it.

Explanation: 

When an uncharged body is placed close to a charged body then it gets induced with an opposite charge and gets attracted.

$(c)$. To move a loaded trolley we have to $\underline{push}$ it.

Explanation:

When a force is applied to a trolley to move it, then the force acting upon it is a kind of push force.

$(d)$. The north pole of a magnet $\underline{repels}$ the north pole of another magnet.

Explanation:

Magnets have a repulsive property. Like poles of two magnets repels each other. Therefore, the north pole of a magnet repels the north pole of another magnet. South pole of a magnet repels the south pole of another magnet.
