Correct Answer: CABD

Solution : The correct choice is the first option.

The logical flow of sentences is:

• Firstly, sentence C establishes the occurrence of thunderstorms and strong winds in northern India.
• Following this, sentence A provides additional context by explaining that these thunderstorms were a significant relief after the region had previously experienced heat wave conditions, highlighting the contrast in weather conditions.
• Then, sentence B adds to the sequence by informing about the Weather Department's forecast of more storms in the upcoming days, indicating a continuation of this weather pattern.
• Finally, sentence D concludes the sequence by mentioning the Weather Department's prediction that the monsoon is likely to arrive in South India soon, providing a broader perspective on weather expectations beyond the current thunderstorms.

Therefore, the correct order is CABD.
