Physical activity and exercise typically lead toa. increased stress b. depression c. higher energy levels d. reduced quality of life

Higher energy levels. C.

Let's try simply answering this through the process of elimination.

We can safely say, that physical activity and exercise are known for their benefits and so for making a positive impact in the lives of individuals rather than a negative impact.

Therefore, we can begin our elimination process by separating the answers into two categories: positives & negatives.

Positives:
- Higher energy levels

Negatives:
- Increased stress
- Depression
- Reduced quality of life

Now, the answer is most likely to be Option C. Higher energy levels. This is as physical activity & exercise are known to make individuals more active and fit whilst stimulating them with an increase in energy levels. However, if you aren't completely sure or you require extra confirmation then you can review why the other options are incorrect by reading the following as displayed below.

Option A is incorrect as physical activity & exercise is known to relieve & decrease stress, not increase it. It helps distract individuals from the stress of their daily lives which in turn aids in relieving stress & momentarily clearing the mind. Therefore, A is false.

Option B is incorrect as physical activity & exercise is known to improve mental health meaning it can't cause or lead to depression. As a matter of fact, it actually stimulates the brain to release dopamine which increases levels of positivity & joy. Therefore, B is false.

Option D is incorrect as physical activity & exercise is known for it's numerous benefits & advantages which actually improve the quality of life, not reduce it. For example, it aids in improving mental health, physical fitness & overall well-being which increases the quality of life. Therefore, D is false.

Hence, Option C. Higher Energy Levels must be the correct answer.
