Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The fundamental frequency of a pipe closed at one end is half that of an open pipe of the same length. Reason (R): A closed pipe has a node at the closed end and an antinode at the open end, restricting allowed wavelengths to \( 4L/(2n+1) \). In the light of the above statements, choose the correct answer from the options given below:

1. A
   Both (A) and (R) are true and (R) is the correct explanation of (A).
2. B
   Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. C
   (A) is true but (R) is false.
4. D
   (A) is false but (R) is true.
