Answer:
One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.
One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.

<h2>B) is the correct option </h2>
Explanation:
The parasympathetic activity is responsible for the body's rest and digestion response when the body is relaxed, resting, or feeding, it basically undoes the work of sympathetic division after a stressful situation
The parasympathetic activity decreases respiration and heart rate and increases digestion
Increased sympathetic activity plays an important role in patho-physiological role in hypertension, particularly in the early stages which is evident by increased heart rate and blood pressure variability
