Solution

The correct option is A increase, increase
The magnitude of induced emf increases with the increase in the number of turns in closed coil. The greater the number of coils, the greater the strength. This is because more the number of coils, more uniformity is obtained in the magnetic field and hence the magnitude of the induced emf is more stronger.
