The position vectors of the points `Pa n dQ` with respect to the origin `O` are ` vec a= hat i+3 hat j-2 hat k` and ` vec b=3 hat i- hat j-2 hat k ,` respectively. If `M` is a point on `P Q ,` such that `O M` is the beisector of `P O Q ,` then ` vec O M` is a. `2( hat i- hat j+ hat k)` b. `2 hat i+ hat j-2 hat k` c. `2(- hat i+ hat j- hat k)` d. `2( hat i+ hat j+ hat k)`
