Final Answer : E, Explanation :  To find the percentage of cat and/or dog lovers who prefer Brand 2 Cola, we add the percentages of cat and dog lovers who prefer Brand 2 Cola: 7.5% (cat lovers) + 12.0% (dog lovers) = 19.5%. Then, we calculate this as a percentage of the total cat and dog lovers: 19.5% / (30.0% + 40.0%) = 19.5% / 70.0% = 27.9%.
