Answer: (B)

The main axis of an inflorescence is called the rachis. This structure serves as the central stem that supports the flowers or flower clusters within the inflorescence. The rachis can branch out to form various types of flower arrangements, facilitating the distribution of flowers and aiding in pollination and reproduction. For example, in a compound raceme or panicle, the rachis connects the main flower stems, providing structural support and organization to the flowering bodies of plants. Understanding the function of the rachis is important because it plays a crucial role in the overall architecture of flowering plants and in the efficient arrangement of flowers for attracting pollinators.
