Explanation

Correct answer: (a) CDBA Correct arrangement: C→D→B→A Final sentence: “Octopuses have three hearts, and two of them stop beating when they swim.” Structure Analysis: · (C) octopuses have three → introduces subject · (D) hearts, and two → continues idea · (B) of them stop beating → specifies action · (A) when they swim → completes condition Grammar Rule: · Noun phrase must be completed first (“three hearts”) · Then pronoun reference (“two of them”) · Followed by verb and condition Example: She has two cars, and one of them breaks down frequently. Final takeaway: Logical noun completion and pronoun reference make CDBA the correct sequence.
