Statement 1: A set from which the values of the variable involved in the inequation are chosen is called the solution set.

Statement 2: A linear inequation variable (or unknown) has exactly one solution.

Which of the following options is correct?

1. Both the statements are true.

2. Both the statements are false.

3. Statement 1 is true, and statement 2 is false.

Assertion (A) : The solution set for :

x + 5 ≤ 10, if the replacement set is {x | x ≤ 5, x ∈ W} is {0, 1, 2, 3, 4, 5}.

Reason (R) : The set of elements of the replacement which satisfy the given inequation is called the solution set.

1. Both A and R are correct, and R is the correct explanation for A.

2. Both A and R are correct, and R is not the correct explanation for A.

3. A is true, but R is false.

4. A is false, but R is true.
