Flower with monadelphous conditon and pentacarpellary ovary are present in China rose family Pea family Potato family Yucca family

Hello Student
Answer is 1. China Rose Family
Firstly we talk about Monadelphous means Fusion of the filaments of stamen to form a bundle. And pentacarpellary means five carpel or pistil
So China Rose Family or Rosaceae Family Shows the Property of Monadelphous but it has five or more carpels so it is pentacarpellary or polycarpellary. While Pea Family or Fabaceae Family is MonoCarpellary; Potato Family or Solanaceae Family shows Bicarpellary and Yucca Family or Agavoideae Family shows Tricarpellary Ovaries then ans closely relate to China Family or Rosaceae.
