Select the correct statement with reference to muscle structure \(I.\) Each myosin is a polymerized protein \(II.\) Many meromyosin constitutes one thick filament (myosin) \(III.\) Each meromyosin's tail is called heavy meromyosin \((HMM)\) and head is called light meromyosin \((LMM)\) \(IV.\) The globular head is an active \(ATP\) ase enzyme and has binding sites for \(ATP\) and active sites for actin Choose the option with correct statements

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
