Solution

The answer is the first one: stronger.

Explanation for each option:

Stronger: Sub-maximal stimuli refer to stimuli that are not strong enough to activate all motor units but can progressively increase in strength to recruit additional motor units. As the stimuli get stronger, more motor units are activated, leading to the production of action potentials in the axons of these additional motor units.
Weaker: Weaker stimuli would not progressively recruit additional motor units. Instead, they would likely activate fewer motor units or none at all if they are below the threshold required to generate an action potential.

Summary: Sub-maximal stimuli are those that get progressively stronger and produce action potentials in axons of additional motor units.
