Answer:
c silent mutation
Explanation:
The given mutation changes the genetic code "GGC" to "GGA". According to the genetic code table, both "GGC" and "GGA" code for glycine. Since both mutated and normal codon code for the same amino acid, that is glycine, the mutation would not have any effect on the function of the gene.
The point mutation that does not affect the function of a gene is called a silent mutation. Hence, the given example represents the silent mutation.
