If a^{\to}\timesb^{\to}=c^{\to} and b^{\to}\timesc^{\to}=a^{\to} then which one of the following is correct? [NDA I 2017]

Correct Answer is : →a,→b,→c are orthogonal in pairs and |→a|=|→c| and |→b|=1

a^{\to},b^{\to},c^{\to} are orthogonal in pairs and |a^{\to}|=|c^{\to}| and |b^{\to}|=1

a^{\to},b^{\to},c^{\to} are non-orthogonal to each other

a^{\to},b^{\to},c^{\to} are orthogonal in pairs but |a^{\to}|\neq|c^{\to}|

a^{\to},b^{\to},c^{\to} are orthogonal in pairs but |b^{\to}|\neq1
