Genes and chromosomes. can you label these chromosomes with the correct genetic terms?

I found the exercise on the internet. Attached is an image with the terms and the representation of the chromosomes mentioned above.

The term for the position a) would be homologous chromosomes. Position b) is gene locus. Position c) is recessive allele because it is represented by a small letter. Position d) is centromere. Position e) is sister chromatids. Position f) is alleles. Position g) is dominant allele because it is represented by a capital letter.

Answer is c just took the test on edgenuity
