Question

Filo · Accepted Answer

Androecium is stamens in the flower which forms a whorl surrounding the gynoecium and is inside the perianth. Stamens can be present as free or fused. The fused stamen can be connate, joined in the same whorl or adnate, joined from more than one whorl.

Monoadelphous stamens are fused into a single, compound structure. When connate stamens are joined partially into two androecial structures, the condition is termed as diadelphous.
Polyadelphous refers to the condition when connate stamens are joined partially into three or more than three groups. If only anthers are fused or joined, it is called as synandrous.

In china rose, filaments are fused to form a stamina tube, thus it is monoadelphous. Therefore, the correct answer is option B.
