B Correct answer
Explanation

Initial volume = 80% of bottle. Let total capacity be V. Initial liquid = 0.8V. Guava = 0.6 * 0.8V = 0.48V. Adding 200mL makes it full, so 0.2V = 200, V = 1000mL. Guava = 0.48 * 1000 = 480mL.

AI explanation

The 200 mL of rum fills the remaining 20% of the bottle, meaning the bottle's total capacity is 1000 mL. Because the liquid initially occupies 80% of the bottle, its volume is 800 mL. Since guava juice makes up 60% of this liquid, the amount of guava juice is 0.60 multiplied by 800 mL, which equals 480 mL.
