The correct answer is: A flammable gasoline-based bomb.<br /><br />Napalm is a highly flammable liquid that was originally developed during World War II as a weapon. It is a mixture of gasoline thickened with a variety of chemicals, making it stick to surfaces and burn intensely. Napalm was used extensively during the Vietnam War, where it was dropped from aircraft in the form of bombs or sprayed from aircraft in the form of a mist. It caused severe burns and destruction, and its use has been widely condemned as a violation of international law.
