What is the lowest temperature at which a liquid gives off sufficient vapors to form a flammable mixture with air in the presence of an ignition source?

A Flash point
B Flammable range
C Reid vapor index
D Autoignition temperature
AI Explanation

The correct answer is A) Flash point. The flash point of a liquid is the lowest temperature at which the liquid gives off sufficient vapors to form a flammable mixture with air in the presence of an ignition source. This is the critical temperature that determines the flammability of a liquid. The other answer choices are not directly related to the lowest temperature for forming a flammable mixture. The flash point is a key safety parameter used in the handling and storage of flammable liquids, and it is an important consideration in Coast Guard Captain's License Examinations. Knowing the flash point helps prevent the risk of fire and explosion.
