The copying mechanism of dna is most likecarving a figure out of wood. dripping water out of a faucet. taking a picture of yourself and of your reflection in a mirror. mixing flour, sugar, and water to make bread dough.

The correct answer is: taking a picture of yourself and of your reflection

This example above can be compared to copying mechanism of DNA-replication in which one strand of DNA (e.g. 3’-5’ orientation) is used as a template to make new strand with opposite orientation (5’-3’). Picture of yourself is a template and a picture of reflection is copied strand.
