Explanation:

The best revision of the given sentence is displayed through option B as it is the one that is correctly punctuated. As per the grammatical rules, a relative clause is preceded and succeeded both by a comma(,). The first comma right after the noun or subject it modifies or describes('Eliana Rodriguez' in the given sentence) and the second after the relative clause('who teaches biology') to mark the beginning of the principal clause('is my favorite..lectures'). Thus, only option B appropriately revises the given sentence and conveys the intended meaning(affiliated to the structure) effectively. Thus, option B is the correct answer.
