Question

Answer 1

Orthostatic hypotension is a drop in blood pressure when changing body position, specifically from sitting to standing.

Step-by-step explanation:

Orthostatic hypotension is a condition characterized by a drop in blood pressure when changing body position, specifically from sitting to standing (option a). When you stand up, gravity pulls more blood down into your legs, and your cardiovascular system has to work harder to keep blood flow to your brain. In some cases, this adjustment doesn't happen properly, leading to a decrease in blood pressure and symptoms like dizziness or loss of balance.
