To solve this problem, we need to analyze each statement regarding skeletal muscle:$\newline \bullet$A. Muscle bundles are held together by collagenous connective tissue layer called fascicle.$\newline$ - This statement is incorrect. The term "fascicle" refers to a bundle of muscle fibers, not the connective tissue. The connective tissue that holds muscle bundles together is called the "epimysium."$\newline \bullet$B. Sarcoplasmic reticulum of muscle fibre is a storehouse of calcium ions.$\newline$ - This statement is correct. The sarcoplasmic reticulum is an organelle in muscle cells that stores calcium ions, which are essential for muscle contraction.$\newline \bullet$
