An endothermic reaction is characterized by its absorption of heat from the surroundings. This means that during the reaction, energy is taken in, which often results in a decrease in the temperature of the immediate environment. As a result, you may feel the surroundings getting cooler as the reaction progresses. This property is a defining feature of endothermic reactions, distinguishing them from exothermic reactions, which release heat energy. The other options do not accurately represent the nature of endothermic reactions, which is why they are not suitable answers.
