question 1 of 8

Explanation:

Labeling the lid is risky because lids can be swapped between plates, leading to misidentification of the culture. Labeling the bottom of the plate ensures the label stays with the agar medium, and including pertinent information is a standard, necessary practice for lab organization.

Answer:

A. Labeling the lid.
