C is not an example of evolution so that is your answer
The answer is transverse wave
Answer:
Can I see the options if it have any
Explanation:
Diploblasty is a state of the blastula in which there are two essential germ layers: the ectoderm and endoderm. Diploblastic living beings are life forms which create from such a blastula and incorporate cnidaria and Ctenophora, earlier assembled together in the phylum Coelenterata, yet later comprehension of their disparities brought about their being put in discrete phyla.
To answer the above:
Diploblastic animals have ectoderm and an endoderm as well as radial symmetry.
D. Electromagnetic waves
<span><span> Generally, Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase.</span><span>The creation of all electromagnetic waves usually begins with a charged particle, which creates oscillating electric and magnetic fields.</span><span>Once they are in motion, the electric and magnetic fields that are charged in particles creates are self-perpetuating: time-dependent change in one field (electric or magnetic) to produce the other.</span></span>
