Why the answer is C, and why the others tempt you.
Feed Conversion Ratio (FCR) is calculated as the total feed consumed divided by the total weight gained: FCR = 2,400 ÷ 800 = 3.0. A lower FCR indicates more efficient feed utilisation. The distractor 0.33 results from inverting the formula, while 2.00 and 4.00 result from arithmetic errors in the division.
