The area of the region (in sq. units), enclosed by the circle $x ^ { 2 } + y ^ { 2 } = 2$ which is not common to the region bounded by the parabola $y ^ { 2 } = x$ and the straight line $y = x$, is\\
(1) $\frac { 1 } { 6 } (24 \pi - 1)$\\
(2) $\frac { 1 } { 3 } (6 \pi - 1)$\\
(3) $\frac { 1 } { 3 } (12 \pi - 1)$\\
(4) $\frac { 1 } { 6 } (12 \pi - 1)$
