An inferior ovary of a flower is situated

Step 1: Analyze the question The question asks where an inferior ovary is positioned relative to the other floral parts (sepals, petals and stamens).

Step 2: Explain the concept The position of the ovary on the receptacle is described by comparing it with the other floral parts:

• Superior ovary (hypogynous flower): The ovary sits above the point where the sepals, petals and stamens attach. Examples are hibiscus and tomato.
• Inferior ovary (epigynous flower): The sepals, petals and stamens attach above the ovary, so the ovary sits below the other floral parts. Examples are cucumber, pumpkin, guava and banana.
• Half-inferior (perigynous) ovary: The ovary sits at about the same level as the attachment of the other floral parts.

Step 3: Apply to the options

• A. Below the floral parts. This matches the definition of an inferior ovary.
• B. Above the floral parts. This describes a superior ovary.
• C. At the same level. This describes a perigynous (half-inferior) ovary.
• D. At the centre. This is not a standard way of classifying ovary position.

Step 4: Answer An inferior ovary is situated below the floral parts.

Tip: "Inferior" means "lower", so an inferior ovary lies lower than the other floral parts. "Superior" means higher. Linking the word to its position makes this easy to remember in the exam.
