Which of the following fats is known for being solid at lower temperatures?

Coconut oil is known for being solid at lower temperatures primarily due to its unique composition of fatty acids. It consists largely of saturated fats, which have higher melting points compared to unsaturated fats found in other oils. This high saturation level allows coconut oil to remain solid at room temperature and even at slightly warmer temperatures, whereas oils like canola, olive, and sesame are predominantly unsaturated fats, causing them to remain liquid at room temperature.

The solid state of coconut oil is often utilized in cooking and baking, where a firmer texture is desired. Additionally, this characteristic makes it popular in the health and beauty industries, where it is used in products that benefit from a solid form at cooler temperatures.
