Which of the following equations is a correct form of the Clausius-Clapeyron equation?

A) $\ln \frac{P_{2}}{P_{1}}=-\frac{R}{\Delta H_{\mathrm{vap}}}\left[\frac{1}{T_{2}}-\frac{1}{T_{1}}\right]$
B) $\ln \frac{P_{2}}{P_{1}}=-\frac{\Delta H_{\text {vap }}}{R}\left[\frac{1}{T_{2}}-\frac{1}{T_{1}}\right]$
C) $\ln \frac{P_{2}}{P_{1}}=-\Delta H_{\text {vap }}\left[\frac{1}{T_{2}-T_{1}}\right]$
D) $\ln \frac{P_{2}}{P_{1}}=\frac{\Delta H_{\text {vap }}}{R}\left[\frac{1}{T_{2}-T_{1}}\right]$
E) $\ln \frac{P_{2}}{P_{1}}=-\frac{\Delta H_{\text {vap }}}{R}\left[\frac{1}{T_{2}-T_{1}}\right]$
