In the plants, due to mutation in the mitochondrial genome causing cytoplasmic male sterility can be influenced by the nuclear gene (Rf),  which is dominant over the cytoplasmic mitochondrial genome. If a male sterile plant  is pollinated by the fertile male plant with homozygous (Rf)condition, the progeny obtained in F1 will have

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;
