To find the limit , we can use the given limit .Let's rewrite the expression as: Now, let . As approaches 0, also approaches 0. So, we can substitute for in the limit: Since approaches 0 as approaches 0, we can use the given limit : The second limit is equal to 1 as approaches 0: Now, we need to find the limit of . As approaches 0, also approaches 0. So, we can use the given limit again: Therefore, the limit is: So, the correct answer is:A.
