Solution

The correct option is D $R - B r$ and $R - I$
As we progress down the periodic table from fluorine to iodine, molecular size increases. As a result, we also see an increase in bond length. As the bond length increases, upon irradiation of light, after absorption the compound emit light in visible region. Hence, R-Br and R-I bond exhibit color when exposed to light.
