The rigth answer is D.
The wavefront or wavefront is an equal phase surface of a wave, i.e., these points have the same travel time from the source. The concept is used to describe the propagation of waves such as sound or electromagnetic radiation (light, radio waves, etc.). In a homogeneous and isotropic medium, in which the waves propagate without deformation, two types of particular waves are distinguished according to whether the wavefronts are spheres (spherical wave) or planes (plane wave).

Hypothesis contributed to the mistaken idea that protein is the genetic material because, with its 20 different amino acids, protein structure could be more variable than that of c.
<h3>What is DNA?</h3>
- Deoxyribonucleic acid is a kind of DNA.
- All known animals and many viruses contain genetic instructions in the form of a polymer called DNA, which is made up of two polynucleotide chains that coil around one another to form a double helix.
- Among the four major categories of macromolecules—along with proteins, lipids, and complex carbohydrates—nucleic acids are one of the four that are essential for all known forms of life (polysaccharides).
<h3>How does DNA get created?</h3>
- The chemical building blocks of DNA are called nucleotides.
- These constituents consist of one of four different nitrogen bases, a phosphate group, a sugar group, and a sugar group.
- DNA strands are built from chains of nucleotides that are bonded together with the phosphate and sugar groups swapped out.
