Answer:

b. intercalated discs connect the muscle fibers together.

Explanation:

Intercalated discs are components of the muscles found in the heart(cardiac muscles).

Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.

Intercalated discs are made of up desmosomes and gap junctions.

Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.
