B Correct answer
Explanation

The Human Genome Project (HGP) reported approximately 2.1 million single nucleotide polymorphisms (SNPs) in the human genome. This number represented the initial catalog of genetic variations discovered during the project. The larger numbers (3.3 billion and 4.2 billion) are closer to the total number of base pairs in the human genome, not SNP counts.
