A planar truss tower structure is shown in the figure.
Consider the following statements about the external and internal determinacies of the truss.
- Externally Determinate
- External Static Indeterminacy $=1$
- External Static Indeterminacy $=2$
- Internally Determinate
- Internal Static Indeterminacy $=1$
- Internal Static Indeterminacy $=2$

- P-False; Q- True; R-False; S-False; T-False; U- True
- P-False; Q- True; R-False; S-False; T-True; U- True
- P-False; Q- False; R-True; S-False; T-False; U- True
- P-True; Q- True; R-False; S-True; T-False; U- True
