Good morning sir. Answer is zero amp. If theta is 90. So flux zero then i=0. But how theta 90. Here B is perpendicular to coil radius. That means B is parallel to area vector of plane of coil. So how theta 90.

Dear student,

The reason for induced current to be zero is not that there is no flux passing through the coil, but that it is not changing with respect to time, hence no emf is induced.
