In the context of assurances, which choice represents a promise: I promised him that the situation would not be repeated in the future?

The statement, "I promised him that the situation would not be repeated in the future," clearly conveys a commitment to a particular course of action or outcome, which is a hallmark of making a promise. Among the choices provided, the one that aligns most closely with this concept is to give one's word that the situation will not happen again.

This choice explicitly indicates a personal commitment or assurance to another party, suggesting that the speaker is willing to stand behind their assertion, highlighting a sense of responsibility and intent. Such language establishes a clear expectation that the speaker will take measures to ensure the described situation is avoided in the future.

In contrast, the other options either lack the definitive aspect of a promise or express uncertainty, making them less relevant to the idea of a commitment.
