• A) \(\sinh ^ { - 1 } ( \sqrt { 5 } ) - \sinh ^ { - 1 } \left( \frac { \sqrt { 5 } } { 6 } \right)\)
• B) \(- \frac { 1 } { 6 } \operatorname { csch } ^ { - 1 } ( \sqrt { 5 } ) - \frac { 1 } { 6 } \operatorname { csch } ^ { - 1 } \left( \frac { \sqrt { 5 } } { 6 } \right)\)
• C) \(\cosh ^ { - 1 } ( \sqrt { 5 } ) - \cosh ^ { - 1 } \left( \frac { \sqrt { 5 } } { 6 } \right)\)
• D) \(- \frac { 1 } { 6 } \operatorname { sech } ^ { - 1 } ( \sqrt { 5 } ) + \frac { 1 } { 6 } \operatorname { sech } ^ { - 1 } \left( \frac { \sqrt { 5 } } { 6 } \right)\)
