Learn Dutch: Ben jij het slachtoffer van de overval? Ja, ik ben het. - Are you the victim of the robbery? Yes, I am.

In English, you can answer with just 'Yes, I am.' However, Dutch linking verbs like zijn (to be) usually require a complement; they cannot just be left hanging. You must use the resumptive pronoun het to fill that slot and refer back to the entire noun phrase, which in this case is het slachtoffer van de overval.

If the question used a de word instead of a het word, would the answer still use het?

Yes, it would still be het. When used as a predicative resumptive pronoun, het acts as a generic placeholder for the previously mentioned noun or adjective. Even if the question was Ben jij de dader? (Are you the perpetrator?), the answer remains exactly the same: Ja, ik ben het.

Is it wrong to just answer with Ja, ik ben?

Yes, that sounds incomplete and unnatural in Dutch. If you use the subject and verb, you must include het. However, you can completely drop the verb phrase and just say Ja or Dat klopt (That is correct) in everyday conversation.
