ANSWER: None of the above options are correct.

Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)

Therefore where HR= 90bpm and SV= 110ml/min,

CO = 90 × 110 = 9900ml/min or 9.9L/min.

EXPLANATION:

CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.

Cardiac output is the product of two variables, stroke volume and heart rate.

STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.

HEART RATE is the count of the number of times the heart beats per minute.
