Which Statement Best Differentiates Between Limiter and Clamper Circuits

Multiple Choice

Which statement best differentiates between limiter and clamper circuits?

A) A limiter limits the both peaks of the output of a given signal, while the clamper limits only one.
B) A limiter sets the limit of the peak output of a given signal while the clamper establishes a dc reference level based on the peak output of the signal from which the ac signal will vary.
C) A limiter sets a dc reference voltage that the ac signal varies upon while the clamper limits the peak output.
D) none of the above
