It would be classified under the Kingdom Plantae so the answer is D
The best answer should be B.
Apparatus in laboratories can be really dangerous, especially the ones which involves electricity.
As a student, he should not just wrap the cord with electric tape, as he might wrap them in a wrong way and possible could hurt himself. So A is not a good answer.
And for C, even though it is a great idea not to use the frayed cord hot plate, but he should also notify the teacher as that hot plate with frayed cord may be passed on and be used for the other students which may pose a risk to them.
And obviously, using the hot plate with frayed cord is super dangerous and he could possibly get electric shock. So D is the incorrect answer.
And it's only left to B, it right to notify the teacher so the teacher can actually either fix it themselves or they wouldn't pass on to other students to use it.

pH = - log [H+]
10^-pH = [H+]
The phenomenon of populations of organisms changing from generation to generation is known as biological evolution.
<h3>What is biological evolution?</h3>
Biological evolution is a scientific term that deals with the change in inherited traits through successive generations in an organism's population. For example, penguins have typical wings over swim-friendly flippers which were there for many generations. It is also called microevolution. Biological evolution is important because it helps us to understand why an organism is the way they are. Mutation, genetic drift, gene flow, and non-random mating are some of the causes of biological evolution. Heredity and Reproduction are the top conditions for biological evolution.
