If four distinct points with position vectors { {\a}}^{\to}, { {\b}}^{\to}, { {\c}}^{\to} and { {\d}}^{\to} are coplanar, then [{ {\a}}^{\to} { {\b}}^{\to} { {\c}}^{\to}] is equal to [11-Apr-2023 shift 2]

Correct Answer is : [→d→c→a]+[→b→d→a]+[→c→d→b]

[{ {\d}}^{\to} { {\c}}^{\to} { {\a}}^{\to}]+[{ {\b}}^{\to} { {\d}}^{\to} { {\a}}^{\to}]+[{ {\c}}^{\to} { {\d}}^{\to} { {\b}}^{\to}]

[{ {\d}}^{\to} { {\b}}^{\to} { {\a}}^{\to}]+[{ {\a}}^{\to} { {\c}}^{\to} { {\d}}^{\to}]+[{ {\d}}^{\to} { {\b}}^{\to} { {\c}}^{\to}]

[{ {\a}}^{\to} { {\d}}^{\to} { {\b}}^{\to}]+[{ {\d}}^{\to} { {\c}}^{\to} { {\a}}^{\to}]+[{ {\d}}^{\to} { {\b}}^{\to} { {\c}}^{\to}]

[{ {\b}}^{\to} { {\c}}^{\to} { {\d}}^{\to}]+[{ {\d}}^{\to} { {\a}}^{\to} { {\c}}^{\to}]+[{ {\d}}^{\to} { {\b}}^{\to} { {\a}}^{\to}]
