Correct Answer - B
`sqrt(-sqrt(3)+sqrt(3+8sqrt(7+4sqrt(3))))`
`impliessqrt(-sqrt(3)+sqrt(3+8sqrt((2+sqrt(3))^(2))))`
`impliessqrt(-sqrt(3)+sqrt(3+8(2+sqrt(3))))`
`impliessqrt(-sqrt(3)-sqrt(((sqrt3)^(2)+(4)^(2)+2xx4xxsqrt(3)))`
`impliessqrt(-sqrt(3)+sqrt((4+sqrt(3))^(2))`
`impliessqrt(-sqrt(3)+4+sqrt(3))impliessqrt(4)=2`
