Answer 1

Right option is (d) Decrease in density of the globules

To explain: Three factors contribute to this enhanced stability of homogenized milk: a decrease in the mean diameter of the fat globules, a decrease in the size distribution of the fat globules, and an increase in density of the globules owing to the adsorption of a protein membrane.
