• A. One
• B. Two
• C. Three
• D. Four

Answer 1

The correct option is B Two

Depending upon the mode of branching of peduncle, the inflorescences are of two main types - Recaulescent and Concaulescent.
When the bract is attached to the stem holding the flower (the pedicel or
peduncle), it is said to be recaulescent; sometimes these bracts or bracteolesare highly modified and appear to be appendages of the flower calyx.
Recaulescences is the fusion of the subtending leaf with the stem holding the bud or the bud itself, thus the leaf or bract is adnate to the stem of flower. When the formation of the bud is shifted up the stem distinctly above the subtending leaf, it is described as concaulescent.

Therefore, the correct answer is option B.
