(1) He forbade me to tell anyone about his plan.
(2) She is forbidden from leaving Canada.
(3) He was forbidden to leave the house, as a punishment.
(4) Women are forbidden from going out without a veil.

So "forbid somebody to do something" is more common. Let's review more "prohibition words" and realize that "forbid" is a special one.
• Prevent somebody from doing something
• Prohibit somebody from doing something
• Keep somebody from doing something
• Preclude somebody from doing something
• Deter somebody from doing something
• Debar somebody from doing something.
• Dissuade somebody from doing something
• Forbid somebody to do something

(A) The only thing against this sentence is "from doing" rather than "to do".
(B) "the" should not be used because the Oath applies to all physicians not just a particular group.
(C) Compare with (A). "Forbid somebody to do something" is used.
(D) Compare with (A). Essentially the same, a fact that usually disqualify both options.
It is also wordy, an argument that only helps eliminate this version.
(E) "forbid that" is not a well-established usage pattern.
