Hint: The flower is the reproductive organ generated by flowering plants. It is sometimes called a blossom or bloom. The primary function of a flower is to carry on reproduction through the development of gametes and provide mechanisms for the union of gametes in a process called fertilisation. Structurally, the flower is fixed to the stem by a pedicel.

Complete Step-by-step answer:

Solitary flower is one flower at a certain position of a plant. This flower appears singly or detached from other flowers by the vegetative area. For example, Trillium grandiflorum.

Racemose is kind of an inflorescence in which major axis continues to grow indefinitely and does not end in flower.” Therefore, it is also called indeterminate or indefinite inflorescence.

The axillary bud(or lateral bud) is an embryonic or organogenic shoot situated in the axil of a leaf. Each bud has the potential to form shoots and may be specialised in generating either reproductive shoots (flowers) or vegetative shoots (stems and branches).

In the cymose kind of inflorescence, the primary axis does not grow on an ongoing basis. A flower is present terminally on the primary axis. The flowers are to bear in a basipetal order. The primary axis has limited growth.

Therefore the correct answer is Option A.

Note: The flower is the individual reproductive organ of a flowering plant. Usually, it is a modified shoot, which contains a corolla, calyx, pistil, and stamen. The primary function of the flower is to generate gametes, undergo fertilisation, and form seeds.
