Choose the correct, for muscle in relaxed position:

Explanation

In the relaxed state of a muscle:Exposed binding sites on actin: This is incorrect. In the relaxed muscle, the binding sites on actin (for myosin) are typically blocked by tropomyosin, preventing cross-bridge formation.Broad H-zone in sarcomere: This is correct. In a relaxed muscle, the H-zone (the region where there is no overlap between actin and myosin filaments) is broad because the actin and myosin filaments are not overlapping much.Formation of cross bridges: This is incorrect in the relaxed state. Cross-bridges are formed when the muscle is stimulated, and the binding sites on actin are exposed due to the action of calcium ions (Ca²⁺).Ca²⁺ released in cytosol: This is incorrect in the relaxed state. In the relaxed muscle, Ca²⁺ is stored in the sarcoplasmic reticulum and not released into the cytosol. Calcium is released only when the muscle is stimulated to contract.
