Correct Answer - C
`(sqrt(3)+1)(10+sqrt(12)(sqrt(12)-2)(5-sqrt(3))`
`implies(sqrt(3)+1)(10+2sqrt(3))(2sqrt(3)-2)(5-sqrt(3))`
`implies(sqrt(3)+1)xx2(5+sqrt(3))xx2(sqrt(3)-1)(5-sqrt(3))`
`implies4(sqrt(3)+1)(sqrt(3)-1)(5+sqrt(3)(5-sqrt(3))`
`implies4[(sqrt(3))^(2)-^(2)][(5)^(2)-(sqrt(3))^(2)]`
`implies4xx2xx22implies176`
