How many possible alleles are at a locus consisting of 3 base-pairs in a diploid

How many possible alleles are at a locus consisting of 3 base-pairs in a diploid

ugh, I am so confused...

So, I guess a locus is just a spot for a gene, so the gene is also considered to consist of 3 bases?

Each "_" could be either an A,T,C, or G.
