I. Kinetin is a degradative substance from DNA II. ABA is present in all plants including lower plants III. Low ratio of cytokinin to auxin favours root formation only IV. ABA is synthesised catabolically through glycolysis pathway Choose the correct combination of options |

(c) ABA is produced in many parts of green plants. Its presence is suspicious in lower plants (bryophytes and pteridophytes). ABA is formed by melvonic acid pathway, not by glycolysis |
