Answer 1

The answer is **a. major histocompatability complex**.The major histocompatibility complex (MHC) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility. The term "major histocompatibility complex" is used to describe the preference for mates with a different kind of immune system because studies suggest that animals (including humans) are attracted to individuals with different MHC genes than their own. This is thought to be advantageous because offspring with more diverse MHC genes will have a broader immune response and be better equipped to fight off a wider range of pathogens. While the other options sound plausible, they are not established scientific terms used in this context.
