Final answer:
Palm oil and trans fats share the characteristic of being solid at room temperature, which is due to their molecular structure that allows the molecules to pack tightly together. Hence the correct answer is option A
Step-by-step explanation:
One characteristic that palm oil shares with trans fats is that both are solid at room temperature. This is because they have high proportions of long-chain fatty acids or, in the case of trans fats, trans double bonds, which allow the molecules to pack together tightly and solidify at room temperature. Saturated fats like palm oil are commonly derived from sources such as coconut oil and meat, and are solid at room temperature due to their lack of double bonds in the carbon chains, whereas unsaturated fats, which are typically of plant origin like olive and peanut oils, are liquid at room temperature because they contain double bonds.
Hence the correct answer is option A
