Vedclass · Answer

(D) The correct answer is $D$. $PGRs$ (Plant Growth Regulators) are not divided into three groups based on their functions. Instead,they are broadly classified into two main groups based on their physiological roles: $1$. Plant Growth Promoters (e.g.,auxins,gibberellins,and cytokinins) which promote growth activities like cell division,cell enlargement,and pattern formation. $2$. Plant Growth Inhibitors (e.g.,abscisic acid) which play a role in plant responses to wounds and stresses of biotic and abiotic origin,and are involved in various growth-inhibiting activities like dormancy and abscission. Therefore,the statement that they are divided into three groups is incorrect.
