What would logically follow if a key indicates a plant has blue flowers with fused petals?

The notion that the plant is likely to be pollinated by insects logically follows from the description of having blue flowers with fused petals. Blue flowers are often associated with insect pollination, particularly by bees, which are attracted to blue hues. The structure of the petals being fused can facilitate the access of pollinators to the reproductive parts of the flower, enhancing the likelihood of pollination by insects.

While other options may present characteristics that some plants might have, they do not directly correlate with the key information about the flower color and petal structure. For example, the type of plant (shrub), its survival in dry environments, or its fragrance do not have a clear connection to its flower color and structure impacting its pollination process. Thus, option B is the most logical consequence of the plant's characteristics stated in the question.
