Explanation

In the phrase "She argued -me about the marriage," the preposition that fits best is "with," making the complete sentence "She argued with me about the marriage." Here’s why "with" is the correct choice:

The verb "argue" typically requires a preposition when it involves two parties engaged in a discussion or dispute. When we say someone argued with another person, it indicates a back-and-forth exchange where both parties have differing opinions or views. In this case, "with" implies a dialogue or debate concerning the subject of marriage, where both individuals are participating in the conversation.

On the other hand, the other options provided do not fit the context appropriately. For instance, "argued for" suggests advocating or supporting a position rather than engaging in a dialogic confrontation, whereas "argued from" does not properly convey a sense of direct contention or discussion between two individuals. Therefore, "argued with" accurately captures the essence of a dispute or conversation involving differing perspectives, which is why it is the correct choice.
