What process involves proteins forming solid masses while tissue consolidates?

The process described involves proteins forming solid masses while tissue consolidates, which is best represented by coagulation. Coagulation refers to the transformation of a liquid into a solid or semi-solid state. In biological contexts, this often involves the denaturation and aggregation of proteins, resulting in the formation of a gel-like structure. This process is crucial in various natural occurrences, such as blood clotting and the hardening of tissues during funeral care practices, where preservation and stabilization of body tissues are vital.

In contrast, fluidization involves the conversion of a material from a solid to a fluid-like state, which does not relate to the formation of solid masses as described. Liquefaction refers to the process of turning solid materials into a liquid, which again does not coincide with the formation of solid masses. Denaturation is the alteration of the natural structure of proteins, which may lead to coagulation, but it does not specifically describe the formation of solid masses. Therefore, the clear connection between coagulation and the solidification of tissues makes it the correct choice.
