Match List I with List II. List I List II A. 2,4-D I. Rooting in stem cuttings B. IBA II. Hastening fruit ripening C. Ethephon III. Increasing sugarcane yield D. Gibberellic acid IV. Preparing weed-free lawns Choose the correct answer from the options given below:

Step-by-step solution

2,4-D is a synthetic auxin widely used to kill dicotyledonous weeds, thus helping in preparing weed-free lawns. IBA (Indole-3-butyric acid) is an auxin used to initiate rooting in stem cuttings. Ethephon is a widely used source of ethylene that hastens fruit ripening in tomatoes and apples. Gibberellic acid is sprayed on sugarcane crops to increase the length of the stem, thereby increasing the yield. Therefore, the correct matching is A-IV, B-I, C-II, D-III. Answer: A-IV, B-I, C-II, D-III
