Given answer is right both on the same side.

Both Go and No Go diameters are combined on a single gage member, so parts can be inspected quickly in one easy operation.

Progressive cylindrical plug gages may be your best choice for checking the internal diameter of parts quickly. This gage design is ideal for high frequency and high volume inspection.

Both Go and No Go diameters are combined on a single gage member, so parts can be inspected quickly in one easy operation.

The progressive gage should smoothly enter the part and then stop at the high limit. Gage members are securely attached to either a taper lock handle or trilock handle with mounting bolts. Progressive cylindrical plug gages are available from .105 up to 8.0 in diameter.

They can be supplied in steel, chrome or carbide materials. Plug gages tolerances range from class xx to zz. Specials and extra length gages are priced on request. Thread Check's expert sales engineers' can assist you with selecting the right gage for your application.

I think option A is wrong, because 'GO' and 'NO GO' gauge are opposite to each other.
