d) the acceptance of new technology that pushed artists to explore new mediums

Explanation:

In Nadar raising photography to art, Daumier uses satire to reflect the acceptance of new technologies that have led artists to explore new media. This is because photography was not seen as an artistic device and was generally excluded from elitist conversations about art. Daumier was also right to say that from Nadar photography would reach new limits and could finally be incorporated into the field of artistic study. This effort that began with Nadar would continue throughout the 19th and 20th centuries, and today photography is one of the most recognized artistic disciplines, free from the elitism suffered by many others.
