Correct option is B
Leveling bolts (also known as
leveling screws) are used to
adjust the height and alignment of machines to ensure stability, precision, and proper functioning. These bolts help in
compensating for uneven surfaces and allow for
fine adjustments to keep the machine level.
While leveling bolts aid in stability, they do not provide
structural rigidity to the machine. Rigidity is achieved through
proper machine design and mounting.
