Which of the following cloud types resembles a woolly appearance at lower altitudes?

Stratocumulus clouds are characterized by their low and often extensive presence in the atmosphere, typically appearing as large, rounded masses that sometimes resemble a woolly or fluffy texture. This low-altitude cloud type can be recognized by its white or gray color and is often associated with relatively stable weather conditions. Their appearance can create a patchy or lumpy sky, which further supports the woolly descriptor.

In contrast, cirrostratus clouds are high-altitude clouds that are thin and wispy, often covering the sky in a veil-like layer. Cumulonimbus clouds, on the other hand, are vertical clouds associated with thunderstorms and have a towering shape rather than a low, woolly appearance. Altostratus clouds are mid-level clouds that typically appear as a uniform gray or blue, layering the sky but lacking the puffy, textured look of stratocumulus.
