Localized heating of the Earth's surface causes warm air to rise by convection.
As the rising air cools and condenses, rainfall occurs. This type of rainfall is known as convectional rainfall.
Hence,
\[
\boxed{\text{Convectional rainfall}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
Note: The image marks option (A) as correct, but this is incorrect. Rainfall caused by localized heating of air is convectional rainfall; thus the provided answer key contains an error.
