Option B is correct: "As a result of his failure to study, Teddy promptly failed his algebra exam.
This is correct because the comma used (after the word "study") separates the independent clause ("Teddy promptly failed his algebra exam") and the subordinate clause ("As a result of his failure to study") in the right way.
The other options contain grammatical errors and they don't even sound right..
Option A has an unnecessary comma after the word "result."
Option C uses the semicolon incorrectly.
Option D, similarly to Option A has an unnecessary comma after the word "result" and is missing a necessary comma after the word "study."
Thus, Option B is correct
