## Step 1The problem is about the process of DNA replication, specifically the role of DNA polymerase III. DNA polymerase III is an enzyme that adds nucleotides to an existing chain during DNA replication.## Step 2However, DNA polymerase III cannot initiate the replication process on its own. It requires a primer to start the replication process.## Step 3The primer is a short strand of RNA that serves as a starting point for DNA synthesis. This primer is laid down by another enzyme called primase.## Step 4The primer is not a DNA primer, but an RNA primer. Therefore, the correct answer is "d. an RNA primer".
