Which DEA number would be correct for a physician?

The correct DEA number for a physician typically begins with a letter that represents the type of registrant, followed by a series of digits. The first character is generally the first letter of the registrant's last name, and the second character often indicates the type of registration, such as "A" for hospitals or "B" for physicians.

In the case of the provided choices, the DEA number beginning with "BG" indicates a registration for a physician. This adheres to the standard format and would be assigned to a medical practitioner. The subsequent digits in the DEA number are part of a sequence that helps to verify its authenticity; however, the combination of letters is significant in identifying the registrant's professional capacity.

Choosing the other options would not align with the conventions of DEA numbering designated for physicians or might not follow DEA requirements for validity. Therefore, the answer with "BG" accurately reflects the established format for a healthcare provider like a physician.
