Pick up the correct statement about the solution on an alkali metal in liquid ammonia

The solution shows paramagnetism which decreases with increasing concentration

The solution is a good conductor of electricity whose conductivity increases on cooling

The solution is a good reducing agnet

All are correct

This current doubles for every `100^@`C rise in temperature

This current is due to minority charge carriers

Reverse saturation current is also known as leakage current

Width of depletion layer increases

The angle of prism is `60^@`

The refractive index of the prism is `n=sqrt3`

For deviation to be `65^@` the angle of incidence `i_1 = 55^@`

The curve of `delta` vs “i' is parabolic
