Which of the following statements about saturated fatty acids is true?

Saturated fatty acids are characterized by having no double bonds between their carbon atoms, which allows them to pack tightly together. This tight packing results in them being solid at room temperature. The carbon chains of saturated fatty acids are saturated with hydrogen atoms, which contributes to their structure and physical properties.

In contrast, fatty acids with one or more double bonds (unsaturated fatty acids) cannot pack as closely due to the kinks in their structure, which makes them liquid at room temperature. Unsaturated fatty acids are commonly found in plant oils, whereas saturated fatty acids are more prevalent in animal fats and certain tropical oils.

This understanding of the structural characteristics and physical properties of saturated fats supports the assertion that they are solid at room temperature, making the first statement accurate.
