Your answer should be I and IV according to your explanation because energy and linear momentum are conserved. There are also spelling errors for "conserved" in I and IV

My school the question says "in an elastic collision" not inelastic ooo, and in an elastic collision both energy and momentum are conserved

The answer is meant to be I and IV. The explanation given also justifies this.
