In an updrift scenario, the most fitting option is B) warm air from the surface rises.
An updrift typically refers to the upward movement of warm air, which occurs because it is less dense than the cooler air surrounding it. As warm air rises, it can contribute to the development of clouds and potentially lead to weather phenomena like thunderstorms if enough moisture is present.
The other options describe different atmospheric phenomena but are not directly related to the concept of updrift.
