Final answer:

An example of protein thermal irreversible denaturation is Lysozyme unfolding, similar to how albumin in egg whites denatures when cooked. The correct option is D.

Step-by-step explanation:

An example of protein thermal irreversible denaturation is Lysozyme unfolding. This occurs when a protein like lysozyme is exposed to high temperatures, which disrupts its three-dimensional structure, often leading to a loss of function.

A common, everyday example is the denaturation of albumin in egg whites when cooked; the protein transforms from a clear, viscous liquid to an opaque, solid form as it is fried or boiled, which is irreversible.
