What is cloud point in fuels?

Explanation:
Cloud point is the temperature at which wax crystals begin to form in fuels like diesel, causing the fuel to become cloudy and to thicken as the crystals grow. This is important in cold conditions because those crystals can clog filters and restrict flow, potentially leading to starting and running problems. The other options aren’t correct because cloud point isn’t about when the fuel ignites (that’s the ignition or flash point), nor its boiling point, nor a color change of the fuel.
