C. Lipid-containing, preservative-free artificial tears used regularly

Rationale: MGD causes a deficient/abnormal lipid layer, so lipid-containing, preservative‑free drops supplement the tear film and are least likely to worsen evaporative DED. The other options (preserved vasoconstrictors, astringents) are more likely to irritate or damage the ocular surface, and heavy daytime ointments can blur vision and trap debris or interfere with normal tear dynamics.
