mutations are traits that are completely different from parents that are always harmful.

Explanation:

To determine the correct description of mutations, we analyze each option:

• The first option incorrectly defines mutations as traits (mutations are changes in DNA, not traits) and claims they are "completely different from parents" (mutations can be subtle changes).
• The second option correctly states that mutations are changes to DNA and can be beneficial, harmful, or neutral.
• The third option is incorrect as mutations are not always harmful; they can be beneficial or neutral.
• The fourth option is wrong as it misdefines mutations as traits and claims they are always harmful (which is not true).

Answer:

B. Mutations are changes to DNA that can be beneficial, harmful, or neutral.
