Choose the correct answer from the options given below:

1. (1) (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
2. (2) (A)-(I), (B)-(III), (C)-(II), (D)-(IV)
3. (3) (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
4. (4) (A)-(IV), (B)-(II), (C)-(III), (D)-(I)

   Option (3) is correct: (A)-(III), (B)-(IV), (C)-(I), (D)-(II).

   Compositae, Umbelliferae, Labiatae, and Cruciferae are older family names (pre-ICN standardization) matched to modern APG/APG IV classifications: Asteraceae, Apiaceae, Lamiaceae, and Brassicaceae, respectively.

   Term Matches

   These represent composite (capitula inflorescences), umbel-bearing, labiate (bilabiate corolla), and cruciform (cross-shaped) flower families, renamed for monophyly.​

   • (A) Compositae: Asteraceae (III), e.g., sunflower, daisy—capitulum heads.​

   • (B) Umbelliferae: Apiaceae (IV), e.g., carrot, parsley—umbel inflorescences.​

   • (C) Labiatae: Lamiaceae (I), e.g., mint, basil—labiate corollas, square stems.​

   • (D) Cruciferae: Brassicaceae (II), e.g., mustard, cabbage—cruciform flowers.​

   Option Analysis

   Option	Mapping	Correct?	Reason
   (1)	A-II, B-I, C-IV, D-III	No	Mismatches Compositae (not Brassicaceae); confuses Labiatae/Umbelliferae. ​
   (2)	A-I, B-III, C-II, D-IV	No	Swaps all; Compositae ≠ Lamiaceae, Cruciferae ≠ Apiaceae. ​
   (3)	A-III, B-IV, C-I, D-II	Yes	Standard matches per taxonomy texts (e.g., Bentham-Hooker to APG).
   (4)	A-IV, B-II, C-III, D-I	No	Inverts pairs; Umbelliferae ≠ Brassicaceae. ​

   Compositae Umbelliferae Labiatae Cruciferae match questions test historical-to-modern plant family names in NEET/GATE Life Sciences, linking old Linnaean terms to APG IV families.

   Family Renamings

   Pre-1910 names reflected floral traits: Compositae (composite heads) → Asteraceae; Umbelliferae (umbels) → Apiaceae; Labiatae (lipped corollas) → Lamiaceae; Cruciferae (cross flowers) → Brassicaceae. ICN mandates single names per family.

   Key Examples

   • Compositae/Asteraceae: Sunflower (Helianthus), 25,000+ species.​

   • Umbelliferae/Apiaceae: Fennel (Foeniculum), schizocarp fruits.​

   • Labiatae/Lamiaceae: Thyme (Thymus), aromatic volatiles.​

   • Cruciferae/Brassicaceae: Radish (Raphanus), myrosin cells.​

   Exam Tip

   Memorize C-A, U-Api, L-Lam, Cru-Bra. Bentham-Hooker systems use old names; modern exams expect both. Practice with 10 major families.​
