In the question given below, there are 2 statements marked as Assertion (A) and Reason (R). Choose the correct alternative from the following options.
Assertion (A)- Examples of conventional commercial sources of energy are coal, petroleum, and fuelwood.
Reason (R)- Examples of non conventional commercial sources of energy are solar energy, wind energy and tidal power.
Answer & explanation
Correct answer: option 4
The correct answer is Option 4: Assertion (A) is false, but Reason (R) is true.
-
Assertion (A) is false because fuelwood is not considered a commercial source of energy; it is typically classified as a non-commercial or traditional source of energy. Coal and petroleum are conventional commercial sources, but fuelwood does not fit into this category.
-
Reason (R) is true because solar energy, wind energy, and tidal power are examples of non-conventional commercial sources of energy. These are renewable sources and are increasingly used in modern energy systems.
