The magnitude of the reflection coefficient is:

• A. \(\left| \rho \right| = \frac{{{V_{max}}}}{{{V_{min}}}}\)
• B. \(\left| \rho \right| = \frac{{\left( {VSWR - 1} \right)}}{{\left( {VSWR + 1} \right)}}\)
• C. \(\left| \rho \right| = \frac{{\left( {VSWR + 1} \right)}}{{\left( {VSWR - 1} \right)}}\)
• D. \(\left| \rho \right| = \frac{{\left| {{V_i}} \right|}}{{\left| {{V_r}} \right|}}\)
