Answer:
b. The bromine (Br2) has reacted with the benzene, leaving fewer bromine molecules in solution.
Explanation:
Colour is caused by absorption of light of the frequency of “complementary colours”. Exactly which frequencies molecules absorb depends on the arrangement of electrons. Obviously, to break the Br-Br bond and the C=C bond in the reactants and replace them with two C-H bonds is a significant reordering of electrons and so the new molecule is no longer able to absorb the same frequencies as previously. Hence, a colour change, in this case from orange to colourless.
In chem it usually would be but it depends on your units and the instructions
