The option that would result in a decreased cardiac output is d) Decreased preload.

Here's why:

Cardiac output is the volume of blood the heart pumps per minute. It's determined by the heart rate (the number of heart beats per minute) and the stroke volume (the volume of blood pumped per beat).

a) Increased sympathetic stimulation of the sinoatrial node would increase the heart rate, thus increasing cardiac output.

b) Decreased end systolic volume would increase stroke volume (since stroke volume = end diastolic volume - end systolic volume), thus increasing cardiac output.

c) Increased heart rate would increase cardiac output, as more blood is being pumped per minute.

d) Decreased preload would decrease stroke volume. Preload refers to the volume of blood in the ventricles at the end of diastole (just before contraction). If there's less blood to pump, the heart can't pump as much blood per beat, which would decrease cardiac output.
