The correct answer is - the air.
The Namib Desert is one of the driest places on the planet and that is due to the cold and dry ocean currents alongside the southwestern part of Africa which are not providing the right conditions for precipitation to occur.
Even though there's no rain, because the Namib Desert is very hot, and the ocean currents very cold, the end result is mist that appears every morning, as well as dew.
The plants living in this desert have evolved in accordance to the conditions, so instead of being dependent on their roots for getting water, they get the majority of the water through their leafs and skin, directly from the air.

Explanation:
Differences in temperature lead to variations in air pressure around the world. Low-pressure areas are created when air rises. It is called low pressure because the weight of the air above the Earth's surface is lower than average. High-pressure areas are created when air sinks. It is called high pressure because the weight of the air is above average when it sinks to the Earth's surface.
Low-pressure areas are associated with cloud and precipitation (rainfall) because:
as the air rises it cools, condenses and forms clouds
the water droplets in the clouds increase in size
they eventually become too heavy to be held and fall as precipitation
The air above the Equator is very hot and rises, creating an area of low pressure. The Equator experiences high amounts of rainfall due to this rising air resulting in a warm and wet equatorial climate (eg the Amazon and Congo tropical rainforests).
High-pressure areas are associated with dry, warm and settled weather conditions. This is because sinking air does not result in precipitation.
