b. Increase heart rate

c. Increase in vasoconstriction (and peripheral resistance)

Expert's answer
e. All the above occur at about the same rate

Short-term adjustments to blood pressure are made by sympathetic nervous system (its actions increase cardiac contractility, heart rate and peripheral resistance) and renin–angiotensin-aldosterone system (RAAS), which is activated by decreasing in kidney filtration rate.
