Final answer:
Homologous chromosomes are separated in meiosis I during Anaphase I by spindle fibers pulling them to opposite poles, resulting in two haploid daughter cells.
Step-by-step explanation:
The statement that best describes how homologous chromosomes are separated during meiosis I is: b) They are pulled apart by spindle fibers to opposite poles. This occurs during an important phase known as Anaphase I, where spindle fibers shorten, allowing each chromosome of the homologous pair to move toward opposite poles of the cell. Following this, telophase I and cytokinesis result in two haploid daughter cells, each receiving one chromosome from each homologous pair.
