If \( a=\sqrt{6}-\sqrt{3}, b=\sqrt{3}-\sqrt{2} \) and \( c=\sqrt{2}-\sqrt{6} \),
(W) then find the value of \( a^{3}+b^{3}+c^{3}-2 a b c \).
(a) \( 3 \sqrt{2}-5 \sqrt{3}-\sqrt{6} \)
(b) \( 3 \sqrt{2}-5 \sqrt{3}-\sqrt{6} \)
(c) \( 3 \sqrt{2}-4 \sqrt{3}+\sqrt{6} \)
(d) \( 3 \sqrt{2}+4 \sqrt{3}+\sqrt{6} \)
