Elevated main generator winding temperature requires a reduction in reactive load from 200 MVAR (out) to 150 MVAR (out) ___

A main generator is operating and connected to an infinite power grid.

Elevated main generator winding temperature requires a reduction in reactive load from 200 MVAR (out) to 150 MVAR (out).

A. increase; larger
B. increase; smaller
C. decrease; larger
D. decrease; smaller
