The option chosen indicates that the Parasympathetic Nervous System decreases gland activity. However, this is not accurate. The Parasympathetic Nervous System actually promotes glandular secretion and enhances gland activity. It is responsible for the 'rest and digest' functions of the body, which include stimulating saliva production, increased secretion from digestive glands, and other glandular functions that aid in digestion and conservation of energy.

For instance, during periods of rest or after eating, the parasympathetic nervous system initiates processes that facilitate food digestion. This includes the release of digestive enzymes and other secretions that are necessary for breaking down food. Thus, the correct understanding should reflect that the Parasympathetic Nervous System increases gland activity rather than decreases it.

In contrast, when considering the other choices, stating that it decreases gland activity or has no effect misrepresents the physiological role of this system. The concept that it only affects muscle activity is also incorrect, as it plays a significant role in glandular function apart from its effects on muscles.
