Final answer:
Constant motor activity associated with mania typically leads to physical exhaustion due to the excessive use of energy and lack of proper rest. Option B is correct.
Step-by-step explanation:
The question pertains to the effects of constant motor activity associated with mania, a symptom commonly found in conditions such as bipolar disorder. When an individual experiences mania, they often exhibit a high level of physical activity, which does not typically lead to improved concentration as one might assume.
Instead, this heightened state of activity over prolonged periods can result in physical exhaustion. This is due to the body's expenditure of energy, which, without proper rest and recovery, leads to fatigue. Conditions like bipolar disorder can indeed affect cognitive functions such as concentration and memory, and patients may exhibit difficulty in learning new tasks or may experience mood disturbances.
Additionally, physical exercise is known to have mental health benefits like reducing stress and improving body image, but excessive, uncontrolled motor activity, as seen in mania, typically leads to exhaustion rather than positive outcomes.
