I: | Its ovary is one-chambered but becomes two-chambered due to formation of a false septum |
II: | There may be variation in the length of filaments within its flowers |
III: | Its flower is zygomorphic |
IV: | Its flowers are located at the rim of the thalamus almost at the same level |
1. | Only I and II are correct |
2. | All I, II, III and IV are correct |
3. | Only I, III and IV are correct |
4. | Only I, II and III are correct |
