Final answer:
The correct answer is e.)During prophase I of meiosis, chromosomes begin to condense, crossing over occurs, homologous chromosomes are formed, and spindle microtubules form.
Step-by-step explanation:
During prophase I of meiosis, several events occur. Chromosomes begin to condense, making them visible under a microscope. Crossing over between homologous pairs occurs, where genetic material is exchanged between homologous chromosomes. Pairs of homologous chromosomes are formed as they align together in a process called synapsis. Additionally, spindle microtubules form to help separate chromosomes during later stages of meiosis. However, homologous pairs of chromosomes do not align at the metaphase plate during prophase I. This occurs during metaphase I.
