In a guitar, two strings \(A\) and \(B\) made of same material are slightly out of tune and produce beats of frequency \(6~\text{Hz}\). When tension in \(B\) is slightly decreased, the beat frequency increases to \(7~\text{Hz}\).  If the frequency of \(A\) is \(530~\text{Hz}\), the original frequency of \(B\) will be:

1. \(524~\text{Hz}\) 2. \(536~\text{Hz}\)
3. \(537~\text{Hz}\) 4. \(523~\text{Hz}\)
