Yes, a.

They are right!

The correct answer is a. the air contains 50 percent of the moisture it can hold before precipitation occurs.

Humidity is a measure of the amount of moisture present in the air. It is typically expressed as a percentage, representing the relative amount of water vapor in the air compared to the maximum amount the air could hold at that temperature.

So, when you have 50 percent humidity, it means that the air currently holds half of the maximum amount of moisture it can hold before precipitation (such as rain) occurs. This value indicates that the air is moderately humid. If the humidity exceeds 100 percent, it means that the air is already saturated with moisture and precipitation is likely to occur.
