Answer
The induced emf is clockwise.
Work Step by Step
$B = (6.00\times 10^{-2}~T/s)~t~\hat{k}$
Note that the magnetic field increases over time and the magnetic field is in the +z direction.
Thus, the magnetic flux through the loop also increases over time
According to Lenz's law, the induced current produces a magnetic field which opposes this change. By the right hand rule, the induced current is clockwise.
Since the induced emf is in the same direction as the induced current, the induced emf is clockwise.
