If a^{\to} = 2i^{\^}-3j^{\^}+k^{\^} , b^{\to} = i^{\^}-j^{\^}+2k^{\^} and c^{\to} = 2i^{\^}+j^{\^}+k^{\^} are three vectors, then |(a^{\to}\timesb^{\to})\timesc^{\to}| =

Correct Answer is : √1139|→a×(→b×→c)|

|a^{\to}\times(b^{\to}\timesc^{\to})|

\sqrt{39}/\sqrt{11}|a^{\to}\times(b^{\to}\timesc^{\to})|

\sqrt{\frac{11}{39}}|a^{\to}\times(b^{\to}\timesc^{\to})|

\sqrt{11} |a^{\to}\times(b^{\to}\timesc^{\to})|
