A)

( \sqrt { 7 } , 3 + 7 \sqrt { 7 } ) , ( 0,3 ) , ( \sqrt { 7 } , 3 - 7 \sqrt { 7 } )

( - \sqrt { 7 } , 3 + 7 \sqrt { 7 } ) , ( 0 , - 3 ) , ( \sqrt { 7 } , 3 - 7 \sqrt { 7 } )

( - \sqrt { 7 } , 3 - 7 \sqrt { 7 } ) , ( 0,3 ) , ( \sqrt { 7 } , 3 - 7 \sqrt { 7 } )

( - \sqrt { 7 } , 3 + 7 \sqrt { 7 } ) , ( 0,3 ) , ( \sqrt { 7 } , 3 + 7 \sqrt { 7 } )

( - \sqrt { 7 } , 3 + 7 \sqrt { 7 } ) , ( 0,3 ) , ( \sqrt { 7 } , 3 - 7 \sqrt { 7 } )
