To complete the answer, E true, others false is the only possible solution:
Suppose A is true. Then B is true; but that means C is false, so A is false. XX
Since A is false, C is also false.
Suppose B is true. Then D is true; but that means B is false. XX
Since A, B and C are false, D is false.
Since A, B, C and D are false, E is true.
Since E is true, F is false.
