Changing from Two-sigma limits to three-sigma limits helps to reduce the probability that defects will be generated by the process. Hence the correct answer is C.

What is a Two-Sigma Limit?

This is used to refer to the inclusion of about ninety-five percent of data plotted on the normal distribution curve.

Three sigma-limit on the other hand is a statistical calculation where data fall within three standard deviations from a mean.

If in a manufacturing firm, the quality control unit issues out a polity to reject products that are within two standard deviations to their accepted mean, then more errors will be captured thus resulting in a lot of loss or defective products.
