Explanation:

The context describes "irreversible" as a mistake that couldn't be undone, harm that couldn't be fixed, and damage that was impossible to put right. Option b matches this definition of being unchangeable or unfixable after occurrence. Option a is incorrect as the context doesn't state it's harmful to everyone, and option c is incorrect as the context doesn't relate to multiple uses or value.

Answer:

b. It cannot be changed or fixed once it is completed.
