A) RNA
B) DNA
C) mRNA
D) Mitosis

Correct Answer: B) DNA

Explanation

The question is asking about what controls the reproduction of cells. The options are RNA, DNA, mRNA, and Mitosis. The correct answer is B, DNA. DNA is found in the nucleus of cells and it contains the genetic information that controls the characteristics of an organism. When a cell reproduces, it must first replicate its DNA so that the new cell will have the same genetic information as the original cell. This process is called DNA replication. Mitosis is the process of cell division, which is controlled by the DNA. mRNA is a type of RNA that carries genetic information from the DNA to the ribosomes, where it is used to make proteins. So, while mRNA is involved in the process of protein synthesis, it does not control the reproduction of cells. Therefore, the correct answer is B, DNA.
