Word for point-by-point response

I saw someone use this word before, but I cannot remember what it is. The word describes this scenario:

  1. Person A makes some points:

    This is 1st point. This is 2nd point. This is 3rd point.

  2. Person B refutes those points, often interleaving the original points:

    This is 1st point.

    1st point is wrong because reasons.

    This is 2nd point.

    2nd point is wrong because reasons.

    This is 3rd point.

    3rd point is wrong because reasons.

I remember reading a word or phrase that decribed Person B’s line-by-line response.

What you described is a rebuttal, or as ab2 pointed out a point-by-point rebuttal.
