Answer :
A safety relief valve is set to open at 150 PSI. Its purpose is to safeguard the air system by releasing excess pressure, maintaining a safe operational environment. (Option B)
How is this so?
Consider your air system to be a balloon. If too much air is pumped into the balloon, it may explode.
A safety release valve functions similarly to a safety feature for that balloon. It's programmed to open and release air if the pressure becomes too high, acting as a safety net for the balloon.
It opens in this case when the air pressure reaches 150 PSI, averting any harm. So it's like having a superhero valve that keeps the air system running smoothly and everything safe.
