Among the options provided, the negatively charged sol is:

negatively Charged Sol: In a negatively charged sol, the dispersed colloidal particles carry a net negative charge. These charges are often due to the presence of ions or anions on the surface of the colloidal particles. The negative charge on these particles can result from various processes, including ion adsorption, ion dissociation, or the release of negatively charged ions during chemical reactions.
