• B. Liliaceae
• C. Malvaceae
• D. Brassicaceae

Answer 1

The correct option is C Malvaceae

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.
Monadelphous stamens are fused into a single, compound structure, for example malvaceae. Solanaceae family is characterized by presence of epipetalous stamens in which filaments of stamens are fused with petals. Liliaceae family is characterized by presence of epiphyllous stamens in which filaments of stamens are fused with perianth. Brassicaceae is characterized by presence of synandrous or polyandrous stamen in which only anthers are fused or joined.
Therefore, the correct answer is option C.
