Correct option is B
According to standard design guidelines and practices, such as those outlined in IS 800 (Indian Standard Code for General Construction in Steel), the minimum spacing between the centers of rivet holes should not be less than 2.5 times the diameter of the rivet holes.
This minimum spacing is specified to:
1. Ensure adequate stress distribution around the rivet holes.
2. Prevent material weakening caused by closely spaced rivets.
