A) D D D
It is my choice , I think I've discussed it before
In summary : arterial and venous dilation ----------> decrease after and pre load
Inflammatory mediators -----------------> decrese cardiac contractility
Althiugh septic shock has different stages , I imply from BP=82/44 mmHg that the patient is in late stages of septic shock.

Preload: -/+ (usually decrease)
Contractility: -
Afterload: - (most of the time) / + (late)
