Answer to Question 1

B

Answer to Question 2

A cloud appears white because cloud droplets scatter all wavelengths of visible light in all directions. As a cloud grows larger and taller, more sunlight is reflected from it and less light can penetrate all the way through. Since little light reaches the underside of the cloud, little light is scattered, and the cloud base appears dark. At the same time, if droplets near the cloud base grow larger, they become less effective scatterers and better absorbers. As a result, the meager amount of visible light that does reach this part of the cloud is absorbed rather than scattered, which makes the cloud appear even darker.
