Your answer: —  Â·  Correct: A

Explanation

The gynoecium is the female reproductive part of a flower, consisting of one or more pistils (carpels). Each pistil comprises a stigma, style, and ovary.

  • Statement I is correct: In a multicarpellary gynoecium, if the pistils are fused together, the condition is called syncarpous (e.g., Mustard, Tomato). If they are free, it is called apocarpous (e.g., Lotus, Rose).
  • Statement II is correct: The stigma is the uppermost part of the pistil and serves as the receptive landing platform for pollen grains during pollination.
  • Statement III is incorrect: While stamens and pistils coexist in bisexual flowers, they are generally distinct whorls. Fusion between stamens and the gynoecium (forming a gynostemium) occurs only in specific plant families like Orchidaceae and is not a characteristic of all flowers.
