(d) l is true but ll false.

Explanation: Degree of static indeterminacy Ds = m + re - 2j.
Hence, m =12, j = 9 and re =6,
Ds = 12 + 6 - (2 x 9) =0,
Degree of kinematic indeterminacy= Dk = 2j - re - m = (2 X 9) - 6 - 0 = 12,
Thus, truss is statically determinate and kinematically indeterminate.

Answer is D.

Ds = Dsi + Dse = - 3+3 = 0 = Statically Determinate.
Dk = 2j - e = 2 * 9-3 = 15 = Kinematically Indeterminate.

The answer is D
m+r-2j=0 (Ds) so statically determinate.
Dk=12 hence kinematically indeterminate.
