Why were photographic prints sepia toned?

sepia process was cheaper than black and white
for improved resistance
it is simply ageing of paper
it is the effect of exposition to sunlight
Sepia toning enhances archival qual­i­ties of the photos. Chem­i­cals are used to convert the metallic silver in the print to a sulfide com­pound, which is at least 50% more stable than silver.
