Explanation:

Most of the world’s deserts are located in the western margins of continents in the subtropics because trade winds that blow in the region shed their moisture on the eastern side. They become dry by the time they reach the western margin of the continent. so, statement 1 is correct.
Most of the tropical western margins are washed by Cold Ocean currents which also tend to stabilize the air over the coast and inhibit cloud formation. so, statement 2 is incorrect.

hence, option 1 is the correct answer.
