The correct answer is "filled with emotion"
Step-by-step explanation:
In grammar, an absolute phrase refers to a set of words that act as a modifier of the noun, which means they describe the agent of the sentence. Besides this, absolute phrases are commonly enclosed by commas and can be moved without affecting the main sentence as they are not directly connected to it. In the case of sentence " Tom, filled with emotion, rang the doorbell" the phrase that acts as an absolute phrase is "filled with emotion" because these are the words that describe "Tom" (subject), also these are enclosed by commas and can be moved to any other position for example "Filled with emotion, Tom rang the doorbell".
