Step 1: Understanding the Question:
Four scrambled sentence parts must be arranged into one connected passage. We need to find the natural opening line and then follow the chain of references between the remaining lines.
Step 2: Key Formula or Approach:
The opening line of a passage usually introduces the main subject on its own, without leaning on a pronoun or a word like "these" or "by" that only makes sense if something earlier has already been said. Later lines should pick up words or ideas from the line right before them.
Step 3: Detailed Explanation:
Sentence 2, "Padre Rotton was an even more striking case," names the subject and reads like the start of a new point being made about him, so it opens the passage.
Sentence 1 follows next: "For all the padre's rhetoric... the padre had a whole tribe of Anglo-Indian first cousins" explains exactly why Padre Rotton is called "a striking case", the irony that a man preaching about the English as God's Chosen People was himself surrounded by mixed-race cousins.
Sentence 4 comes after that: "These included James Rotton... the twenty two Muslim sons of his convert cousin, Felix Rotton" uses the word "these" to point straight back to "a whole tribe of Anglo-Indian first cousins" in sentence 1, so it must sit right after sentence 1.
Sentence 3 closes the passage: "By various Indian wives... besieging the British Residency in Lucknow" explains how those cousins came to exist (through various Indian wives) and adds the closing historical detail about the rebellion.
Step 4: Final Answer:
Following the chain, subject introduced, then irony explained, then cousins named, then wives and rebellion described, the order is 2, 1, 4, 3.
\[ \boxed{\text{2, 1, 4, 3, option B}} \]
