Following are given some prediction about stress response which ultimately generate ROS;
a) Stress response activates the scavenging mechanism by ROS , these ROS is responsible for activating self-generation mechanism by using RBOH
b) ROS have a negative effect on plant growth, development, and yield
c) Almost every stress leads to the activation of ROS and its signal transduction
d) ROS indirectly induce acclimation mechanisms

ROS using respiratory burst oxidase homolog (RBOH) or NADPH oxidase for Self- generation mechanism by some other processes , which are involved in ROS generation such as,
A) The amino-terminal cytoplasmic domain of RBOH proteins contains four serines (Ser) that can be phosphorylated by CDPKs and two EF hands that can bind calcium directly
B) As ROS generation such as H2O2, by putting electron for oxidising oxygen into the free radicals, these electron generation by oxidising NADPH and FADH2 in the cytosolic carboxy terminal of RBOH protein
C) The elevation of calcium and ROS levels during the early stages of the stress response activates protein kinases and phosphatases
D) ROS activated Ca2+ channel leads to Ca2+ influx from apoplastic space to cytosol
Arrange the correct order of following steps involve in ROS generation;
