To answer the question, we need to match each label with the correct description of the phase of mitosis it represents. Since the image depicts the late stage of cell division with the title 'D - Telophase,' we will use that information to guide our matching process.Step 1: Understanding the Phases of MitosisMitosis is divided into several phases:- Prophase: Chromatin condenses into visible chromosomes, and the mitotic spindle begins to form.- Metaphase: Chromosomes line up at the metaphase plate, and spindle fibers attach to the centromeres.- Anaphase: Centromeres split, and sister chromatids (now individual chromosomes) are pulled to opposite poles.- Telophase: Chromosomes arrive at the poles, begin to decondense, and are enclosed in two new nuclear envelopes.Step 2: Matching Descriptions to PhasesNow, let's match the descriptions to the correct phase:Label A:A. Centromeres are split apart, and sister chromatids are pulled to opposite poles of the cell. - This description matches Anaphase.B. The chromosomes that were doubled become attached to the spindle fiber by their centromeres. - This description matches Metaphase.C. Chromatin in the cell coils into chromosomes that can be seen. - This description matches Prophase.D. Sister chromatids are separated and contain identical copies of DNA. - This description is a bit vague as it could apply to both Anaphase (where sister chromatids are actively separated) and Telophase (where they have already been separated). However, since the image is titled 'D - Telophase,' we can infer that this description is intended to match Telophase.Final Answer:Label A corresponds to the description for Anaphase, which is "A. Centromeres are split apart, and sister chromatids are pulled to opposite poles of the cell."
