The increasing venous return is proportional to the size of the myocardium

None of the answers are correct

The force of a contraction is proportional to the pre load of the ventricle

The venous return and ventricular preload lead to an increase in stroke volume

The force of a contraction is proportional to the initial length of the cardiac muscle fibres
