FM uses class______ amplifiers and AM uses class ______ amplifiers.(a)

1.	FM uses class______ amplifiers and AM uses class ______ amplifiers.(a) C, C(b) A, C(c) C, A(d) AB, CThe question was posed to me in unit test.I'd like to ask this question from Frequency Modulation Vs. Amplitude Modulation in chapter Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» The correct choice is (c) C, A For explanation: The constant envelope of the transmitted signal ALLOWS efficient class C amplifiers. However in AM, it is critical to MAINTAIN linearity between the applied message and amplitude of transmitted signal. Therefore, class A or AB are USED for AM systems.
