• I. Mustard (Brassicaceae):
  • Placentation: Parietal (False septum/Replum forms). Matches W.
  • Corolla: Valvate or Imbricate (often generalized as Valvate in matching questions relative to others). Matches D.
  • Pair: I - D - W.
• II. Pea (Fabaceae):
  • Aestivation: Vexillary (Papilionaceous). Matches C.
  • Placentation: Marginal. Matches Z.
  • Pair: II - C - Z.
• III. China Rose (Malvaceae):
  • Aestivation: Twisted. Matches B.
  • Placentation: Axile. Matches Y.
  • Pair: III - B - Y.
• IV. Sunflower (Asteraceae):
  • Flower Type: Disc florets have Tubular corolla. Matches A.
  • Placentation: Basal. Matches X.
  • Pair: IV - A - X.

Step 2: Verification:
The sequence is: I-D-W, II-C-Z, III-B-Y, IV-A-X. This matches Option (B).
