Answer:

The answer is option A. 99L/min

Explanation:

Cardiac output is the product of heart rate and stroke volume. Written as

CO = HR x ST

where CO is cardiac output

HR is heart rate (beats/min)

ST is stroke volume (L/beats)

CO = ?

HR = 90beat/min

ST = 110ml/beats = 110L/ beat x 0.01= 1.1L/beat

Substituting the values of HR and ST into the equation. We have

CO = 90beat/min x 1.1L/beat

CO = 99L/min

Cardiac output is 99L/min.
