Answer:
Mono-unsaturated fat
Step-by-step explanation:
Monounsaturated fats are merely fat molecules with one unsaturated carbon bond in the molecule, often called a double bond as well.
Oils containing these fats are usually fluid at ambient temperature, but when cooled, they begin to become solid.
Olive, peanut and canola oil are instances of oil forms containing mono-unsaturated fats.
