This question can be solved logically that "top outer members of a pin-jointed truss always take compression and the bottom outer members take tension" & no single member can transfer the whole load acting on the structure so option D and E can be neglected.

This can't be solved. In order to perform the method of section, reactions should be solved first, however, it can't be solved because information is not enough. We need the angle of force and another one dimension of the truss.

Yes, correct @Denzil.
In order to solve the external rxns at least the angle or one of the truss side must be given.

By section method cut EB and DB solve it's each section separate you will find the same.
