Read the following statements and choose the following option: 1. Ethylene is synthesized by tissues undergoing senescence 2. Cytokinins promote apical shoot growth 3. Ethylene promotes dormancy in seeds 4. Fruit ripening is enhanced by ethylene

Options

  1. ABoth 1 and 4 is correct
  2. BOnly 4 is correct
  3. COnly 2 is correct
  4. DOnly 3 is correct

Correct answer

A. Both 1 and 4 is correct
