C Correct answer
Explanation

Yes, it is correct. The temperature at which a substance ignites and begins to burn is called the flash point. The flash point of wood is 572 degrees. Once wood reaches its flash point, it creates a substance which reacts with oxygen to create a flame. The flame heats the wood, which then spreads the flame. This process explains how fires can spread even in very cold weather. Lightning and earth quakes are the main reasons for this.
