The correct Answer is:
To solve the question regarding the occurrence of a single ovule in an ovary towards the upper end of its cavity, we will analyze the options provided and identify the correct type of placentation. ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the type of placentation that occurs when there is a single ovule located at the upper end of the ovary's cavity. 2. **Reviewing the Options**: - **Basal**: In basal placentation, the ovule is located at the base of the ovary. - **Apical**: In apical placentation, the ovule is situated at the top (upper end) of the ovary. - **Marginal**: In marginal placentation, the ovule develops along the ridge on the ventral side of the ovary. - **Parietal**: In parietal placentation, the ovules are attached to the walls of the ovary. 3. **Identifying the Correct Option**: Since the question specifies that the ovule is located towards the upper end of the cavity of the ovary, we can conclude that this matches the definition of apical placentation. 4. **Final Answer**: Therefore, the correct answer to the question is **apical**.
