The type of mutation that occurred between the original strand and the new strand of DNA is a **substitution** mutation.
In this case, the third codon has changed from "CCC" in the original strand to "ACC" in the new strand, indicating that one nucleotide (C) was replaced by another (A) without any additional nucleotides being added or removed.
