Heya...!
polysome is a complex formed when several ribosomes are attached to a single mRNA.
you might be knowing that a ribosome has two unequal subunits. these two units come together only during protein synthesis i.e., transfer of information from mRNA to polypeptide.
so, for two subunits of ribosomes to attach, Mg+2 ion is required.
CORRECT CHOICE IS D
HOPE THIS HELPS YOU.
