Correct Answer:
A. Stops
The correct answer is Stops.
Why 'Stops' is correct: In English grammar, when a sentence contains a future tense in the main clause (e.g., "We will go out") and a time clause introduced by conjunctions like "when," "as soon as," or "until," the verb in the time clause is typically in the simple present tense, even though it refers to a future action. This is a common rule for future time clauses.
Why other options are incorrect:
- 'Would Stop' is generally used for hypothetical situations or past habits, not for future time clauses of this type.
- 'Stopped' is the past tense and does not fit the future context established by "We will go out."
- 'Stopping' is a present participle and would require an auxiliary verb (e.g., "is stopping") to form a continuous tense, but even then, "when it is stopping raining" is grammatically awkward and incorrect in this specific construction.
