The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Monadelphous Condition**: - The term "Monadelphous" refers to a condition in flowering plants where the stamens are united by their filaments into a single group. This means that all the filaments of the stamens are fused together, forming a single structure. 2. **Understanding Monothecous Condition**: - The term "Monothecous" indicates that there is only one anther (the part of the stamen that produces pollen) per stamen. This means that the flower has a single, undivided anther. 3. **Identifying Families with These Conditions**: - The question asks which plant families exhibit both Monadelphous and Monothecous conditions. - The **Malvaceae** family is known for having a large number of stamens that are united by their filaments (Monadelphous condition). Additionally, they typically have one anther per stamen (Monothecous condition). 4. **Examples of Other Families**: - In the **Liliaceae** family, there are usually six stamens that are free, not united (not Monadelphous). - In the **Solanaceae** family, there are five free stamens (not Monadelphous). - In the **Asteraceae** family, there are also five free stamens (not Monadelphous). 5. **Conclusion**: - Therefore, the correct answer to the question about which family exhibits both Monadelphous and Monothecous conditions is the **Malvaceae** family.
