100 H6/g5.
100 = BASIC SIZE.
H6 = tolerance for the hole.
g5 = tolerance for the shaft.
So option B is correct.

Explanation:

According to India standard specifications, the notation "100 H6/g5" represents a fit tolerance for a mechanical part. The number before the letter indicates the basic size, while the letters indicate the tolerance class. In this case, the basic size is 100 mm.

Understanding Basic Size:
The basic size refers to the theoretical or nominal size of a part. It is the size at which the part is designed to function. In this case, the basic size is 100 mm, which means that the part is intended to have a size of 100 mm.

Understanding Tolerance Class:
The tolerance class is represented by the letters after the basic size. In this case, "H6/g5" represents the tolerance class. The letter "H" denotes the hole (internal) tolerance, while the letter "g" denotes the shaft (external) tolerance. The number after the letter represents the grade of tolerance.

Interpreting the Tolerance Class:
In the given notation, "H6/g5," the numbers 6 and 5 represent the grade of tolerance. The smaller the number, the tighter the tolerance.

In this case, the hole tolerance class is H6, which means that the actual size of the hole can deviate from the basic size by a maximum of 6 micrometers. Similarly, the shaft tolerance class is g5, which means that the actual size of the shaft can deviate from the basic size by a maximum of 5 micrometers.

Conclusion:
Based on the given specifications, the notation "100 H6/g5" indicates that the basic size of the part is 100 mm, and the tolerance class for the hole is H6 (allowing a deviation of 6 micrometers) and the tolerance class for the shaft is g5 (allowing a deviation of 5 micrometers). Therefore, the correct answer is option 'B' - the basic size is 100 mm.
