Question
Two statements labelled as Assertion (A) and Reason (R)
are given. Read both the statement carefully and select the correct answer with the help of the codes. Assertion (A): Use of electric vehicles is being promoted. Reason (R): Electric vehicles are more environments friendly.Solution
The assertion (A) is true because the use of electric vehicles is being promoted. The reason (R) is also true because electric vehicles are indeed more environmentally friendly compared to traditional vehicles. However, the reason (R) doesn't directly explain why the use of electric vehicles is being promoted. There could be various reasons for promoting electric vehicles, including reducing air pollution, dependence on fossil fuels, and promoting sustainable energy sources. Therefore, while both statements are true, the reason is not a direct explanation of the assertion.
