The correct response is:

They are part of the lined-up chromosomes in mitosis.

Sister chromatids are the identical copies of a chromosome that are linked together at the centromere and are separated during mitosis. They do not form during metaphase (that occurs during the S phase of the cell cycle), they do not make up the mitotic spindle (which is composed of microtubules), and they are not daughter cells (which are formed after the separation of sister chromatids).
