Homologous chromosomes are a pair of chromosomes that are similar in size, shape, and gene content. In Figure B, the two chromosomes are of similar size and shape, and have the same genes in the same order, just with different alleles (represented by different letters). Thus, Figure B represents homologous chromosomes. In Figure A, the two chromosomes are not similar in shape, and either have different genes (choice C) or the same genes in a randomized order (choice D), so they do not represent homologous chromosomes. In Figure E, the two chromosomes have different letters, but also have a different number and arrangement of genes, so they also do not represent homologous chromosomes.
