Answer: keeps growing.
- A keeps growing
- B stops growing
- C has one flower
- D bears no flowers
Correct answer: A. keeps growing
Explanation: In racemose types the main axis continues to grow and bears flowers laterally.
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).
