Correct answer: B

Explanation

The Rolled Throughput Yield (RTY) is calculated using the formula: RTY = (Output / Input) * (1 - (Defects Repaired + Scrap) / Input). In this case, the calculation shows that the RTY is 72.66%. The other options do not match the correct calculation and therefore are incorrect.
