The point of location of a short-circuited stub on the line is given by:

• A. \(\dfrac{{\phi - \pi \mp {{\cos }^{ - 1}}\left| K \right|}}{{2\pi }}.\dfrac{\lambda }{4}\)
• B. \(\dfrac{{\phi + \pi \mp {{\cos }^{ - 1}}\left| K \right|}}{{2\pi }}.\dfrac{\lambda }{4}\)
• C. \(\dfrac{ \pi \mp cos^{-1} |K| }{\pi}. \dfrac{\lambda}{2}\)
• D. \(\dfrac{ \phi+\pi \mp cos^{-1} |K| }{\pi}. \dfrac{\lambda}{4}\)
