C Correct answer
Explanation

Process capability (Cp) is defined as the specification width divided by 6 times the process standard deviation. This formula shows how many 6-sigma intervals fit within specification limits. A capable process typically has Cp at least 1.0, meaning 6 sigma fits within specifications. The 6 sigma relationship is fundamental to process capability analysis.
