Explanation:

Aseptic technique aims to prevent contamination. Incubating plates lid - side down prevents condensation from dripping onto the culture. Flaming culture tubes before and after transfer sterilizes the opening. Holding open tubes at an angle reduces airborne contamination. Holding the tube cap in hand instead of placing it on the countertop avoids countertop - borne contamination. Flaming the wire loop until it glows red sterilizes it. All these are correct aseptic procedures.

A. A - E are all correct procedures to do
