Reproduction is one of the characteristics of life. Which of the following choices is an example of reproduction? A. Skin cells dividing.
B. Development of a tadpole into a frog.
C. Bacterial cells dividing.
D. Copying of DNA during DNA replication.

C, bacterial cells dividing

Explanation:

because these are simple, one celled organism, they don't reproduce with male and female, instead they go through mitosis which is when a cell divides into two to reproduce. while A does include this, since skin belongs to a bigger organism it doesn't count as reproduction.
