  1. A
    Peak and Peak together – systolic and diastolic blood pressures.
  2. B
    Peak – Initiation of left atrial contraction only.
  3. C
    Complex – One complete pulse.
  4. D
    Peak – Initiation of total cardiac contraction.

Solution & Step-by-step Explanation

The complex represents ventricular depolarization, which leads to ventricular contraction. Since one ventricular contraction corresponds to one heartbeat (and thus one pulse), the complex represents one complete pulse.
