To determine the correct answer, we need to understand the meaning of the words and the context of the sentence.

The sentence states that a code of ethics governing the behavior of physicians during epidemics did not exist until 1846. It then mentions the American Medical Association.

Let's examine the options:

A) Rescinded: This means to revoke, cancel, or annul. It doesn't make sense in this context since the sentence is talking about the creation of a code of ethics, not its revocation.

B) Promulgated: This means to make known or to officially announce. It is commonly used when referring to the publication or declaration of rules or laws. Given the context, this option seems to be the most appropriate.

C) Presupposed: This means to assume something as true or to take something for granted. It doesn't fit in the sentence because we are discussing the establishment of a code of ethics, not assumptions or presumptions.

D) Depreciated: This means to decrease in value or to disparage. It doesn't make sense in this context since we are discussing the creation of a code of ethics.

E) Implied: This means to suggest or indirectly express something. It doesn't fit the context since we need a word that indicates an official action taken by the American Medical Association.

Based on the explanations above, the correct answer is B) promulgated, which means officially announced or made known.
