The correct answer is: No sooner did the sun rise than the birds start chirping.
The word “no sooner” indicates that the action of the second clause (the birds start chirping) happened immediately after the action of the first clause (the sun rose). This is called a “sequence of events”. In a sequence of events, the verb in the second clause is in the simple past tense, regardless of whether the action is happening now, in the past, or in the future.
The other options are incorrect because they use the wrong verb tense. Option A uses the past participle “risen”, which is used to form the perfect tenses. Option B uses the present tense “is”, which is not appropriate for a sequence of events. Option C uses the plural form “do”, which is not appropriate for the singular subject “sun”. Option D uses the third person singular form “does”, which is not appropriate for the plural subject “birds”.
In conclusion, the correct answer is: No sooner did the sun rise than the birds start chirping.
