The air holds little water vapor and is relatively dry.
The air holds little water vapor and is relatively dry.

The amount of water vapor in the air is 90% of what the air can hold.
The amount of water vapor in the air is 90% of what the air can hold.

The dew point temperature is 90% of the air temperature.
The dew point temperature is 90% of the air temperature.

The temperature must rise in order for air to become saturated with water vapor.

Answer 1

The correct conclusion is:

The amount of water vapor in the air is 90% of what the air can hold.

This is because relative humidity is a measure of how much water vapor is in the air compared to the maximum amount of water vapor that the air can hold at a given temperature. In this case, with a relative humidity of 90%, it means the air is holding 90% of its capacity for water vapor at the given temperature of 70 degrees.
