  2. BA-4;B-3;C-1;D-2
  3. CA-3;B-1;C-4;D-2
  4. DA-3;B-4;C-2;D-1

Correct answer

A. A-3;B-4;C-1;D-2

Step-by-step solution

The medullary rhythmicity area controls the basic rhythm of respiration. The pneumotaxic center regulates the rate and pattern of breathing. The apneustic center prolongs inhalation. Chemoreceptors detect changes in blood pH and CO2 levels.
