Question

select the image for the location where all of your solid wastes/ trash from a lab should go.

Explanation:

Solid waste from a lab should not go down the sink as it can clog pipes or cause chemical - related issues. It also should not be left on the classroom floor. It should be disposed of in a proper trash container. Since no trash - container image is fully shown here but by elimination, the sink and classroom floor are incorrect options.

Answer:

Neither of the provided options (sink, classroom floor) is correct. Solid waste should go in a proper trash bin.
