Energy partitioning between two photosystem protects them from quick dessipation or quick inactivation this energy partitioning take place by a protein kinase that can phosphorylate a specific threonine residue on the surface of LHCII, what is the role of LHCII in phosphorylated and non-phosphorylated state?

a.) LHCII in phosphorylated state migrate towards the PSI in the unstacked region and delivers energy to the PSI 

b.) LHCII in nonphosphorylated state moves back to the grana and delivers energy to the PSII

c.) LHCII in phosphorylated state migrate towards the PSII in the stacked region and delivers energy to the PSI 

d.)  LHCII in nonphosphorylated state moves towards the stroma lamellae unstacked region and delivers energy to the PSII 

Which of the following combination is CORRECT?
