a. True
b. False
Acid precipitation is caused by the release of pollutants such as sulfur dioxide and nitrogen oxides when fossil fuels are burned. These pollutants combine with water in the atmosphere to form acids, which can fall to the earth as precipitation.
The statement in the question is True. Acid precipitation can indeed be traced back to the burning of fossil fuels. When we burn fossil fuels like coal, oil, and gas, they release pollutants into the atmosphere. These pollutants include sulfur dioxide and nitrogen oxides, which can combine with water in the atmosphere to form sulfuric acid and nitric acid. These acids can fall to the earth in the form of precipitation, such as rain, snow, or fog, hence the term 'acid precipitation'. This process can have harmful impacts on the environment, including pollution of bodies of water and damage to vegetation.

Any substance that tastes unpleasant in water solution, turns blue litmus paper red, reacts with some metals to release hydrogen, combines with bases to create salts, and stimulates chemical processes is considered an acid. Here among the given options, NaOH is a base. The correct option is D.
Any hydrogen-containing material that has the ability to donate a proton (hydrogen ion) to another chemical is considered an acid. A base is a molecule or ion that can take up an acid's hydrogen ion. Typically, sour tastes help to identify acidic chemicals.
An acid is not NaOH. It is categorized as a base, more specifically a strong base, because it can receive protons from any proton donor and completely dissociates into sodium and hydroxide ions in an aqueous form.
Thus the correct option is D.
