Solution
The correct option is B II only
Cardiac muscles are present only in heart tissue and are responsible for maintaining the rhythmicity of the heart.Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine and bladder.Striated muscles are the ones in which the contractile fibrils in the cells are aligned in parallel bundles so that their different regions form stripes visible in a microscope. Muscles of this type are attached to the skeleton by tendons and are under voluntary control.
