Answer: ovary.
- A ovary
- B stigma
- C style
- D anther
Correct answer: A. ovary
Explanation: The ovary is the basal part of the carpel that houses the ovules.
In a dicot stem, vascular bundles are arranged in a single ring (with cambium between xylem and phloem, enabling secondary growth); in a monocot stem, bundles are scattered throughout with no cambium, so monocots can't undergo secondary growth (no wood formation).
