The control terminal (pin 5) of 555 timer IC is normally connected to ground through a capacitor (0.01μF). This is to
A. Protect the IC from inadvertent application of high voltage
B. Prevent false triggering by noise coupled onto the pin
C. Convert the trigger input to sharp pulse by differentiation
D. Suppress any negative triggering pulse
