The given option that has molecules that are solid at room temperature is; D: Saturated Fats
<h3>Molecules at room temperature </h3>
Fatty acids are organic compounds that are poorly soluble in water but soluble in organic solvents.
The two main types of fatty acids are Saturated fatty acids and Unsaturated fatty acid.
Saturated fatty acids contains no double bond in their carbon chains and as such they are solids at room temperature.
Meanwhile, Unsaturated fatty acids contains double bonds in their carbon chains and are thus liquids at room temperature.
The missing options are;
A) Both saturated and unsaturated fats
B) Cholesterol
C) Saturated fats
D) Unsaturated fats
