The correct answer is option 2) i.e. DABC.

• D is the first sentence because it introduces the subject of the passage - the cause of thunder.
• A mentions thunder as an act by deities. A also mentions the word 'early', which indicates that the causes explained in A must be the most ancient causes as per chronology. So, A should come before B and C.
• Lucretius's life-span is known to be from c. 99 BC – c. 55 BC. Clearly, as per chronology, B would come before C, since C talks of a 19^th century theory (just 2 centuries before, we are in the 21st century right now).
