The correct Answer is:
To determine whether the statement "Hilum is the region through which ovule attached with funiculus" is true or false, we can analyze the components involved: ### Step-by-Step Solution: 1. **Understanding the Terms**: - **Hilum**: This is the scar or the point of attachment on the seed where the ovule connects to the funiculus. - **Funiculus**: This is the stalk that connects the ovule to the placenta within the ovary of the flower. 2. **Analyzing the Relationship**: - The hilum serves as the junction between the ovule and the funiculus. It is the specific area where the ovule is attached to the funiculus. 3. **Conclusion**: - Since the hilum is indeed the region where the ovule attaches to the funiculus, the statement is **true**. ### Final Answer: The statement "Hilum is the region through which ovule attached with funiculus" is **true**. ---
