14. 

The slope of log-magnitude asymptote changes by - 40 dB/ decade at a frequency ω1. This means that

[A]. a double pole is present
[B]. a pair of complex conjugate poles is present
[C]. either a double pole or a pair of complex conjugate poles is present
[D]. a pole or zero at origin is present

Answer: Option C
