All of the following would be considered symptoms (rather than signs) except:
a. cough
b. sensitivity to light
c. hot flashes
d. acidosis

C. Acidosis

Explanation:

A symptom is a version of the manifestation of a sickness given by the patient. It can vary from patient to patient and is subjective. The signs come from the examination of the patient and are objective and measurable throughout a system of units ( C, mm Hg, other). Acidosis is a sign because it requires laboratory tests.
