In a gas turbine cycle with two stages of rehearing. working between maximum pressure \[{{p}_{1}}\] and minimum pressure \[{{p}_{4}},\] the optimum reheat pressure would be:

• A. \[{{({{p}_{1}}{{p}_{4}})}^{1/3}}\] and \[{{({{p}_{1}}{{p}_{2}})}^{2/3}}\]
• B. \[{{(p_{1}^{2}{{p}_{4}})}^{2/3}}\] and \[{{({{p}_{1}}p_{4}^{2})}^{1/2}}\]
• C. \[\sqrt{{{p}_{1}}{{p}_{4}}}\] and \[{{p}_{1}}\sqrt{{{p}_{4}}}\]
• D. \[{{({{p}_{1}}{{p}_{4}})}^{1/2}}\] and \[{{({{p}_{1}}{{p}_{4}})}^{2/3}}\]
