How?
It should be indeterminate.
Because there is no dimensions are given.
Here will be some horizontal thrust which we will calculate by taking moment.

Here if we consider the equilibrium of pt. C,
In x direction, -f(cb)- f(cd)Cos 8 = 0.
& in y direction, -f(cd)Sin 8 = 0.
This gives, f(cd) = 0.
Therefore, f(cb) = 0.
Hence, option(C) is correct.

Hence, option(C) is correct.

Apply equation pf equilibrium at joint c. Hence there is no force at BC.

As f(bc)sin0 = zero at vertical equilibrium forces = 0.
Therefore f(bc) = 0.
Therefore f(bc) = 0.

At joint C there in neither any external force nor any support to give reaction. Hence BC and DC are zero force members as there is no other force to balance the member forces.

What is meant by truss?

At joint C there is only 2 members meet which are non collinear and there is no external force or reaction act at that joint. So the both member carry 0 force.

When we consider equilibrium at B it means a force of 100tN is in the member BD in the opp. Direction since there is no force acting at any section of the member BC so no force is required to make the equilibrium at c so the force in the member BC is zero.

There is no force on the joint C, so force in the member BC is zero.
