DS-160 unlawful presence on approved Nunc Pro Tunc

My I-94 expired due to passport expiration because of which I had to go through Nunc Pro Tunc (NPT) approval. My NPT petition was approved with a backdated I-94 and thus avoiding any gap in I-94 dates. Later this year, as part of the visa renewal process, I got my I-797. I’m filling in DS-160 and there is a question on unlawful presence:

“Have you ever been unlawfully present, overstayed the amount of time granted by an immigration official or otherwise violated the terms of a U.S. visa?”

Should i answer this as no, since there is no gap in I-94 dates or should i answer it as yes since I overstayed I-94 dates before correction done by NPT
