Correct option is A
Explanation-
A syndrome refers to a set of interrelated traits that appear together across individuals or contexts.
In evolutionary biology, we often describe:
1. Dispersal syndrome (traits related to dispersal)
2. Domestication syndrome (traits in domesticated animals/plants)
3. Pollination syndrome (traits in flowers attracting specific pollinators)
These suites of traits evolve together and serve a coordinated functional or ecological purpose.
Incorrect Options-
Option b - Trait flexibility: Refers to the ability of a single trait to change depending on context — not a suite of traits.
Option c - Plasticity: Describes how an individual trait can vary due to environmental factors — again, not about multiple correlated traits.
Option d - Character displacement: Evolutionary change that reduces overlap between species (e.g., in sympatry) — related to competition, not a suite of traits within a species.
Final Answer:
Option a: A syndrome
