Consider the following statements with respect to synchronous machines. State whether these statements are true or false.(a) Armature reaction is demagnetising when a generating machine supplies zero power factor lagging current.(b) Armature reaction is magnetising when a generating machine supplies zero power factor leading current.(c) Armature reaction is mostly cross-magnetising, though it has a small demagnetising component, when a generating machine supplies unity power factor current.

• A. (a) False, (b) True and (c) False
• B. (a) True, (b) True and (c) True
• C. (a) False, (b) True and (c) True
• D. (a) True, (b) True and (c) False
