If a^{\to} and b^{\to} are respectively the internal and external bisectors of the angles between the vectors -i^{\^}+2j^{\^}-2k^{\^} and 3i^{\^}+4j^{\^} and |a^{\to}| = 2/3 \sqrt6 , |b^{\to}| = 2/3 \sqrt3 , then one of the values of a^{\to}-b^{\to} is

Correct Answer is : 23(−^i+2^j−2^k)

1/{10}(-8i^{\^}+11j^{\^}-2k^{\^})

1/{15}(9i^{\^}-11j^{\^}+3k^{\^})
