Indeterminacy = no.of unknown forces - no. of equilibrium equation.
No.of unknown forces = 3(for fixed) +2(one for each roller support).
Indeterminacy = 5 - 4(3(no. of equilibrium equation) + 1 for internal hinge).
= 1.
No.of unknown forces = 3(for fixed) +2(one for each roller support).
Indeterminacy = 5 - 4(3(no. of equilibrium equation) + 1 for internal hinge).
= 1.

Unknown reactions = fix(3)+rollers(2) + internal hinge (1 horizontal reaction) = 6.
D. O. Indeterminacy =6-3=3 =>(D).
D. O. Indeterminacy =6-3=3 =>(D).

Degree of indeterminacy = r-3+ no of hinges.
= 5-3+1 = 3.
Or degree= 3m + r -3j + n.
= 3(3) +5 -3(4) +1 = 3.
= 5-3+1 = 3.
Or degree= 3m + r -3j + n.
= 3(3) +5 -3(4) +1 = 3.

The correct answer is B.
D = r - 3 - (m-1),
= 5 - 3 - (2-1),
= 1.
D = r - 3 - (m-1),
= 5 - 3 - (2-1),
= 1.
