A cloud of marked vertical development (often anvil-shaped) would be classified as _______________.

A cumulonimbus
B cirrus
C altocumulus
D cirrocumulus
AI Explanation

The correct answer is A) cumulonimbus. A cumulonimbus cloud is a tall, vertically developed cloud with a characteristic anvil-shaped top. This type of cloud is associated with thunderstorm activity and often indicates the presence of strong upward air currents and the potential for severe weather. The other options, cirrus, altocumulus, and cirrocumulus, are not typically characterized by marked vertical development or an anvil shape.
