The wire as shown in figure is bent in the shape of a tent, with `theta=60^(@)` and `L=1.50m` and is placed in a uniform magnetic field of magnitude `0.300T` perpendicular to the table rigid but hinged at points `a` and `b`. If the tent is flattened out on the table in `0.100` sec, then

A

Average induced emf in the wire during this time is`6.75V`

B

Average induced emf in the wire during this time is clockwise (as seen from top)

C

Average induced emf in the wire during this time is anticlockwise (as seen from top)

D

Average induced emf in the wire during this time is `2.75V`
