The Correct Option is B

Solution and Explanation

Step 1: Understanding thread measurement.
Thread gauges are typically used for the measurement of thread size and pitch, but for precise measurement of the thread characteristics (such as thread profile, pitch, and geometry), a tool room microscope is the most effective instrument.
Step 2: Why tool room microscope.
A tool room microscope allows for high-precision measurements and can be used to examine the detailed geometry of threads, including pitch, lead, and profile. It is capable of providing the accuracy required for high-precision threads.
