The recommended antibiotics for the treatment of anthrax include Penicillin, Ciprofloxacin, and Doxycycline due to their effectiveness against Bacillus anthracis, the bacterium responsible for anthrax.

Penicillin has a long history of use in treating infections caused by gram-positive bacteria, including anthrax. For patients who are allergic to penicillin, Ciprofloxacin, a fluoroquinolone antibiotic, serves as an excellent alternative because it is effective against a broad spectrum of bacteria and has good intracellular penetration.

Doxycycline, a tetracycline antibiotic, is also recommended for anthrax treatment because it has demonstrated effectiveness in both cutaneous and systemic forms of the infection. It is particularly important in cases of inhalational anthrax, where prompt treatment is critical.

The combination of these three antibiotics takes into account the potential for resistance and the need for efficacy against different forms of the disease. The other options do not include the most effective and recommended agents for anthrax, which are specifically the antibiotics listed in the correct answer.
