Which choice would best support the claim made in this sentence, given the information in the paragraph?

• A. NO CHANGE
• B. having a melting point of only 232°C
• C. with its unique molecular structure
• D. provided its atomic mass of approximately 118 units

Correct Answer: B

Explanation:

(B) The sentence is stating that tin remains a liquid in the 1,100°C bath. So a statement about tin's melting point explains why tin reacts this way. Choices (A), (C), and (D) provide irrelevant facts about tin.
