Which outcome limits heat storage when basking seals experience reduced insulation?

A)Increased blood flow via vasodilation
B)Elevated metabolic rate's internal heating
C)Enhanced countercurrent heat exchange
D)Accelerated brown fat thermogenesis impact

💡 Explanation

Vasodilation near the skin’s surface increases heat loss, because peripheral blood vessels widen, releasing core body heat. This limits heat storage, rather than increasing it; therefore, heat escapes, rather than countercurrent exchange retaining it.
