During a DNA replication experiment, a researcher uses a DNA polymerase that lacks 3' to 5' exonuclease activity. Which of the following statements is likely true regarding the fidelity of DNA replication in this scenario?

A. The replication process will be highly accurate due to the presence of the DNA polymerase.

B. The lack of proofreading activity will increase the rate of mutations in the newly synthesized DNA.

C. The DNA replication process will be halted due to the inability to correct mismatches.

D. The incorporation of nucleotides will be less efficient compared to a polymerase with proofreading activity.

Which of the following combinations is the most accurate based on the statements?
