1)Range chart illustrates the weak area in the construction process.ans-option B

2)If the item recorded is a fraction of unacceptable parts made in a batch of larger parts, the appropriate control chart is the: percent defective chart (ans-option C)

3)Acceptance sampling :-Acceptance sampling is a major component of quality control and is useful when the cost of testing is high compared to the cost of passing a defective item or when testing is destructive. It is a compromise between doing 100% inspection and no inspection at all.

Acceptance sampling lets the lot of acceptable quality into the manufacturing area and screens out lot that are not acceptable.

ans-Both A and B

I hope this would help you,but if you have any doubt regarding this,you can surely ask. :)
