Explanation:
A bolt of uniform strength is a bolt that has the same strength throughout its length. The strength of a bolt is determined by the cross-sectional area of the bolt, which is a measure of the amount of material in the bolt. If the cross-sectional area of the bolt varies along its length, then the strength of the bolt will also vary along its length.
To develop a bolt of uniform strength, the following factors should be considered:
1. Core diameter of threads
The core diameter of threads is the diameter of the unthreaded portion of the bolt. If the core diameter of threads is kept equal to the diameter of the unthreaded portion of the bolt, then the cross-sectional area of the bolt will be the same throughout its length, and the strength of the bolt will be uniform.
2. Nominal diameter of threads
The nominal diameter of threads is the diameter of the threaded portion of the bolt. If the nominal diameter of threads is kept equal to the diameter of the unthreaded portion of the bolt, then the cross-sectional area of the bolt will be the same throughout its length, and the strength of the bolt will be uniform.
3. End conditions
The end conditions of the bolt can also affect its strength. If one end of the bolt is fixed and the other end is free, then the strength of the bolt will be different at the two ends. To develop a bolt of uniform strength, both ends of the bolt should be fixed or both ends should be free.
Conclusion:
Keeping the core diameter of threads equal to the diameter of the unthreaded portion of the bolt is the correct option to develop a bolt of uniform strength. This ensures that the cross-sectional area of the bolt is the same throughout its length, and the strength of the bolt is uniform.

The options a & c are correct.
As in order to develop a Bolt of uniform strength,we have to maintain same cross sectional area throughout the length,thus, keeping both the core diameter and nominal diameter of threads equal to the diameter of unthreaded portion of the bolt.
