I agree.

The dark gray cloud that blankets the sky and often generates precipitation is called a cumulonimbus cloud. This type of cloud is associated with thunderstorms and can produce heavy rain, lightning, thunder, and even hail or tornadoes.

To determine the name of this cloud, you can start by understanding the different types of clouds. Clouds are classified based on their appearance and altitude. One way to identify the type of cloud is by its shape. Different cloud types have distinct shapes, ranging from flat and layered to puffy and towering.

In the case of a dark gray cloud that generates precipitation, you can narrow down the options to the cumulus or cumulonimbus clouds. Cumulus clouds are often white and fluffy, whereas cumulonimbus clouds are larger and more vertically developed, giving them a characteristic anvil-shaped or tower-like appearance.

To confirm if it is a cumulonimbus cloud, pay attention to other associated weather phenomena. These clouds are often associated with thunderstorms and can produce intense rainfall, thunder, lightning, and other severe weather conditions.

Once you have observed the cloud's appearance and associated weather conditions, you can conclude that a dark gray cloud that blankets the sky and generates precipitation is likely a cumulonimbus cloud.
