Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R Assertion A : Hydrogen is an environment friendly fuel. Reason R : Atomic number of hydrogen is 1 and it is very light element. In the light of the above statements, choose the correct answer from the options given below (1) Both A and R are true and R is the correct explanation of A. (2) A is true but R is false (3) Both A and R are true but R is NOT the correct explanation of A. (4) A is false but R is true

1. Both A and R are true and R is the correct explanation of A.
2. A is true but R is false
3. Both A and R are true but R is NOT the correct explanation of A.
4. A is false but R is true

Correct answer: Both A and R are true but R is NOT the correct explanation of A.

Solution

Hydrogen is indeed considered an environmentally friendly fuel because it produces only water when burned, making it a clean energy source. However, the atomic number and lightness of hydrogen do not directly explain its environmental benefits, which is why the reason provided does not serve as a correct explanation for the assertion.
