Answer 1

Option A is correct.
SPC is employed to control statistics of machine operations.

Answer 2

C. SPC uses control charts to identify process correctness.

SPC is used for measuring and controlling the quality during a manufacturing process.

During manufacturing, quality data can be obtained for measuring and controlling the quality.

This information is plotted on a graph with pre-determined control limits and variations are identified.

If data falls within the control limits then everything is considered to be normal but if it falls outside the control limits, it can indicate the cause of the variation and necessary steps can be taken to fix it.
