a. Dahlia
b. Sunflower
c. Marigold
d. China rose

Answer 1

Hint: We can say that the group or the cluster of the flowers arranged on a stem that is serene of a lead branch part or it can be an intricate procedure of branches' divisions. We can say that it is the altered part of the shoot of seed florae in which there exists the formation of flowers morphologically.

Complete answer:
The modifications can include the factors like and the sort of the phyllotaxis and the internodes and distinctions in the magnitudes, solidities, distensions, adnations, connotations, and reduction of the chief and tributary axes.
- A solitary flower is seen in China rose.
- We came across the word termed as the capitulum. We can define this term as involucre, which is cup-shaped, it is formed by bracts made use in enclosed a solo female flower and a sum of male flowers.
- The capitulum (which is also called the head) bears numerous sessile and minor florets. The receptacle is the name given to the central axis, which becomes flat. The ray florets (another name of Peripheral florets) are neuter or pistillate and zygomorphic.
- Besides, disc florets are said to be bisexual and actinomorphic. We can say that it is a sort of racemose inflorescence. The families of dahlia, sunflower, marigold, and Asteraceae can be examples.
- We came to know that Capitulum inflorescence occurs in plants like Dahlia, Sunflower, Marigold. However, when two lateral divisions progress on the two sides of the lethal flower, it is called the Dichasial cyme. It occurs in plants like jasmine.

Hence, the correct answer is option (D).

Note: Thus, inflorescence can also define as the propagative slice of a shrub that stands a collection of flowers in a precise form. Thus, we can conclude that every type of plant consists of a specific part in it, which allows the plant to complete its functions. We can tell that the Capitulum inflorescence and Dichasial cyme are examples of such plant parts.
