Question 1
Oils and fats both belong to the lipid group. What separates them?
The right answer is the one marked above.
It is the state at room temperature. A lipid that is solid at room temperature is called a fat; one that is liquid is called an oil.
The source is not the test. Coconut oil and sesame oil come from plants, but so does the solid fat in some plant foods — the name follows the state, nothing else.
