Correct option is B
A. Insects are more specialised than plants
Most insect herbivores (P–Y) interact with only 1 or 2 plants.
Plants (A–J), on the other hand, are connected to multiple insects.
So, insects are more specialised, meaning they have narrower diets or fewer interactions.
Statement A is correct.
B. There are no obligate interactions in this network
A species with a single link may still be involved in an obligate interaction.
However, the network does not provide evidence about physiological or ecological dependency.
Hence, we cannot confidently say there are no obligate interactions.
Statement B is not reliably inferable from the diagram.
C. The community is modular
Modularity implies the presence of clusters or compartments.
We can observe that certain groups of plants interact mainly with a specific subset of insects (e.g., A–E mostly with P–T, F–J mostly with W–Y).
These dense intra-group interactions and few between-group interactions indicate modularity.
Statement C is correct.
D. Missing links always represent absence of interaction
In ecological networks, absence of a line does not prove absence of interaction.
It might simply be unobserved or under-sampled.
Hence, this assumption is too strong.
Statement D is incorrect.
