D)aluminum.
E)alum AND aluminum.

Accepted Answer

Alum (aluminum potassium sulfate) is the most commonly used adjuvant in vaccine manufacturing. It is effective in stimulating an immune response, and has been used for over 70 years with a good safety record. Alum works by forming a depot at the injection site, providing a slow release of the antigen and enhancing the recruitment of immune cells to the site. Other adjuvants, such as oil-in-water emulsions, have been developed for specific vaccines, but alum remains the most commonly used.
