Answer:
The correct answer is option D, that is, the updraft stage.
Explanation:
All the thunderstorms, regardless of their type, undergo three phases. These are the developing phase, the mature phase, and the dissipation phase. The initial phase of a thunderstorm is the developing stage or the cumulus stage.
The second phase is the mature stage, in this, the warmed air rises spontaneously until it attains a region of warmer air and can elevate no more. The final phase is the dissipation stage, in this the thunderstorm is subjugated by the downdraft.
