A. Increases in overlap favor more cross-bridges to form, increasing muscle force. muscle force. effect on muscle force. fiber) lengths.

Explanation:

Physiologists Alfred Gordon and Fred Julian and Andew Huxley investigated on the strianed muscle's contraction properties, to demonstrate the way the muscle lenght is affected by changes in overlap between myocin and actin causing the number of cross-bridges increase, increasing muscle's force as well.

No cross-bridge disruption is caused, nor litlle differences or minimal overlap so B, C and D options are not correct.
