Read the following statements and choose the following option: 1. Apical dominance prevents lateral buds from growing 2. Auxins inhibit parthenocarpy 3. 2,4-D is used to kill monocotyledonous plants 4. Auxin also controls xylem differentiation and helps in cell division.

Options

  1. AOnly 1 and 4 are correct
  2. BOnly 2 is incorrect
  3. COnly 3 is correct
  4. DBoth1 and 3 is correct

Correct answer

A. Only 1 and 4 are correct
