Microgel, also called fisheyes, is a lump of non-dispersed polymer.

Explanation:
A lump of non-dispersed polymer in a dispersion is called a microgel, with fisheyes being an alternate name for the same phenomenon. The statement directly identifies microgel and notes it is also known as fisheyes, which is exactly the term described. A gel refers to a crosslinked network swollen with solvent, not a discrete lump of non-dispersed polymer, and resin describes a viscous, polymeric material rather than a separate particle or aggregate. So the term that best matches this description is microgel.
