I think it is B. variable inspection,

Thanks

This is an example of variable inspection. If the testing machine had a light that showed green when the parts were acceptable, then it would have been attribute inspection. We don’t know whether sampling or 100% inspection is taking place. A variable is an actual measurement of some characteristic of a part. An attribute is a yes or no determination of whether the part is good or bad.

thanks for invition ,,,,,,,,,, my choice is option B

Since mentioned as readings are recorded, the right answer will be Variable Inspection

It is understood that the completed printed circuit assembly (finished product) is being inspected by the inspector. As it is a finished product, it will not become process control. As the results are only 3 readouts, it cannot be varaible. So it is only attribute inspection. As there is no information about the inspection plan, it is not clear whether it is part of 100% inspection or sample inspection.
