Option A is correct since animal fats most commonly include saturated fats that have a high melting point and are solids at room temperature.

Option B is incorrect since plant lipids generally are unsaturated lipids and melt at a low temperature. So they are generally liquids at room temperature.

Option C is incorrect since lipids do not exist as gases at room temperature.

Option D is incorrect since lipids do not exist in the plasma state at room temperature.
