Choose the correct answer from the options given below: Column IColumn II AHilumIBasal part representing the junction of chalaza and funicle BMicropyleIIJunction between ovule and funicle CNucellusIIISmall pore at the tip where integuments are absent DChalazaIVCentral mass of parenchymatous cells containing abundant reserve food

Step 1: Analyze the parts of the ovule as studied in angiosperm reproduction (Sexual Reproduction in Flowering Plants). - A. Hilum represents the junction where the body of the ovule attaches to the funicle (stalk). Hence, A matches with II. - B. Micropyle is the small opening or pore left by the integuments at the apex of the ovule through which the pollen tube enters. Hence, B matches with III. - C. Nucellus is the central mass of nutritive parenchymatous tissue enclosed within the integuments, containing abundant reserve food. Hence, C matches with IV. - D. Chalaza is the basal part of the ovule located opposite to the micropylatory end. Hence, D matches with I. Step 2: Match the pairs correctly: - A-II, B-III, C-IV, D-I. Therefore, Option 1 is the correct answer.
