Assertion and Reason are given in following questions. Each question have four option. One of them is correct it. (1) If both assertion and reason and the reason is the correct explanation of the Assertion. (2) If both assertion and reason are true but reason is not the correct explanation of the assertion. (3) If the assertion is true but reason is false. (4) If the assertion and reason both are false. Assertion: Mountain roads rarely go straight up the slope. Reason: slope of mountains are large, therefore, more chances of vehicle to slip from roads. (A) 1 (B) 2 (C) 3 (D) 4

The assertion states that mountain roads rarely go straight up the slope. In order to evaluate this statement, think about the construction and design of mountain roads and how they navigate steep terrain.

Consider the reason provided, which is that slopes of mountains are large, therefore increasing the chances of vehicles slipping from the roads. Consider whether this reason adequately explains the assertion, or if there might be other factors at play in the design of mountain roads.

Now, compare the assertion and the reason to determine if the reason is a correct explanation of the assertion or if there are other factors to be considered. Consider whether the reason is true or not, and whether the assertion is true or not.

Based on your understanding and evaluation of the assertion and reason, choose the option that best represents their relationship: (A) 1 - Both the assertion and reason are true, and the reason is the correct explanation of the assertion. (B) 2 - Both the assertion and reason are true, but the reason is not the correct explanation of the assertion. (C) 3 - The assertion is true, but the reason is false. (D) 4 - Both the assertion and reason are false. The correct option is (B) 2, because both the assertion and reason are true, but the reason is not the only explanation for the assertion. Mountain roads are designed with many switchbacks and gradual curves to manage the steep terrain, not just because of the possibility of vehicles slipping from the roads.
