Non-infectious diseases lack pathogen transmission

Steps:

• Identify non-infectious diseases as those caused by genetics, lifestyle, or environment, not pathogens like bacteria or viruses.
• Evaluate statement 1: Likely correct if it describes non-contagious nature, as these diseases do not spread person-to-person.
• Evaluate statement 2: Likely incorrect if it implies prevention solely by hygiene, which targets infectious diseases.
• Evaluate statement 3: Likely correct if it notes causes like poor diet or injury, aligning with non-infectious origins.

Why C is correct:

• C (1 and 3 only) matches definitions where non-infectious diseases are non-transmissible (1) and arise from non-pathogenic factors (3).

Why the others are wrong:

• A includes 2, but hygiene does not prevent non-infectious diseases.
• B excludes 3, ignoring valid non-pathogenic causes.
• D excludes 1, overlooking the non-contagious core trait.

Not enough information on exact statements 1-3 for full verification.

Final answer: C
