Which of the following uses geometric protocol for character selection?

Correct option is B

→ Truss analysis uses a geometric protocol where specific body landmarks of fish are connected in a network pattern.
→ This creates a truss matrix used for morphometric comparisons.
→ Helps in identifying population differences and stock structure.
Information Booster:
→ Highly accurate for detecting shape variations even within the same species.
→ Useful in fisheries biology, taxonomy, and stock management.
→ Often combined with multivariate statistical techniques.
Additional Information (Other Options):
(a) Cluster analysis: Groups data but does not use geometric landmark protocols.
(c) Component analysis: Generic dimensional tool, not shape-specific.
(d) PCA: Reduces dimensionality; not a geometric protocol itself.
