The plan given below, shows office for six officers namely A, B, C, D, E

and F. Both B and C occupy offices to the right of the corridor (as one enters the office block) and A occupies

the office to the left of the corridor. E and F occupy offices on opposite sides of the corridor but their offices

do not face each other. The offices of C and D face each other. E does not have a corner office. F's office is

further down the corridor than A's, but on the same side.

If E sits in his office and faces the corridor, whose office is to his left?
