In the subterranean caves of Mount Vesper, bioengineers study a diploid crystal beetle whose iridescent shell tint is governed by a single autosomal gene locus with four distinct alleles: C1, C2, C3, and C4. Extensive cross-breeding demonstrates a strict linear dominance hierarchy among these alleles, expressed as C1 > C2 > C3 > C4. Considering that every individual in this population is diploid, what are the total number of possible distinct diploid genotypes and the total number of distinct phenotypes that can exist for this single trait?

A) 16 genotypes and 8 phenotypes

B) 8 genotypes and 4 phenotypes

C) 10 genotypes and 4 phenotypes

D) 6 genotypes and 3 phenotypes
