Three hinged arc mean?

We know that D = R-S.

So, support reaction is 4, equilibrium equations 3, because it is hinged.

So, D = 4-4 = 0.

It is statistical.

since support reactions are 4 and equilibrium equations were 3 and because of a hinge 1 additional equilibrium will be added So,
D = R-S.
R = 4.
S = 3+1 = 4.
D = 4-4 = 0.
Statically determinate.

Why option A is right?

Why it was statically determinate structure?
