An electromagnetic torque is produced as an interaction between a flux and current. The angle between flux and current is $$45^\circ$$. If this angle is change to 30, flux increases by 100% and current reduces by 25%, then the torque

A

reduces to 66.7% of the original

B

increases to 81.6% of teh original

C

reduces to 81.6.7% of the original

D

reduces to 54.4% of the original
