question 3
hereditary diseases are defined as
diseases that may or may not be passed down from parent to child
diseases common to a local area due to environmental factors.
diseases inherited, or passed down, from parent to child.

Explanation:

Hereditary diseases are specifically those that are inherited. The key characteristic is passing from parent to child. The first option is incorrect as hereditary diseases are passed down (not just may or may not). The second option refers to environmental - related diseases (not hereditary). The fourth option refers to contagious diseases (spread through contact, not hereditary).

Answer:

diseases inherited, or passed down, from parent to child.
