Which sign is most indicative of arterial insufficiency in the leg?

Explanation:
Arterial insufficiency reduces blood flow to the leg, so the skin and tissues feel cool because warm arterial blood isn’t reaching them. A cold leg is a classic and most specific sign of decreased arterial perfusion, often with weak or absent pulses and pallor. The other signs point more to problems in the venous system or fluid overload: a warm leg suggests inflammation or venous congestion, edema is typical of venous or lymphatic issues, and heaviness is commonly seen with venous insufficiency. So the cold leg best indicates arterial insufficiency.
