Answer
a) $\bf Clockwise$.
b) $\bf Upward$.
c) $\bf Downward$.
Work Step by Step
$$\color{blue}{\bf [a]}$$
By Lenz's law, the induced current will be created to oppose the decrease or the increase of the magnetic flux inside the loop.
And since the magnetic flux increases by closing the magnet bar, the induced current should create a magnetic flux that opposes the original flux.
This means that the induced current in the loop is $\bf clockwise$ from above.
$$\color{blue}{\bf [b]}$$
Since the magnetic fields, the induced and the original, oppose each other, the force exerted on the loop is a repulsive force whose direction is $\bf upward$.
$$\color{blue}{\bf [c]}$$
According to Newton's third law, the force exerted on the magnet by the loop equals the force exerted by the magnet on the loop but in the opposite direction.
Thus, the direction of the force exerted on the magnet is $\bf downward$.
