Human ear can hear sound having frequency range from $20 \ Hz$ to $20 \ kHz$.

The human hear responds to sounds with frequencies in the range from 20 Hz to 20,000 Hz. This is called the audible range of the human ear.

the Audible range  of frequency for human ear is 20Hz to 20000Hz 

The audible frequency range for human ear is from 20Hz to 20,000Hz , as out of the given frequencies , only frequency of 50000Hz doesn't lie in audible range , therefore it cannot be heard by human ear .

The human hear can respond to minute pressure variations in the air if they are in the audible frequency range, roughly 20 Hz to 20,000 Hz. The vibrations above or below this range is not audible by human.

Humans cannot hear sound of every frequency. The range of hearing for a healthy young person is 20 Hz to 20,000 Hz. This is called audible range of frequency. So, human can hear sound of frequency 100 Hz.

Some animals like whale, octopus and rhino have special hearing abilities and can hear sounds below $20\ Hz$, i.e., the infrasounds.

Humans can hear sounds having frequencies between the range of $20\ Hz$ and $20,000\ Hz$. The sounds above and below this range are inaudible to humans. The sounds below the range of $20\ Hz$ are called infrasounds and the sounds above the range of $20,000\ Hz$ are called ultrasounds. Both are inaudible to humans.

The range of audible frequency is 20 Hz - 20,000 Hz.
In the first case frequency of the tuning fork will be 200 Hz. 
In second case it will be 60 Hz.
In third case frequency will be 1 Hz ,which is out of the audible frequency range.

Sound of vibrations of pendulum lies in infrasonic range while sound of bees lies in audible range.
