Answer:
B
Explanation:
Protons of atoms are the atomic particles with a positive charge while electrons bear a negative charge. Protons are found in the nucleus together with neutrons (that have no charge). They are held together by strong nuclear forces that overcome the repulsive forces between the positive charges in the nucleus. The electrons orbit around the nucleus and are kept in orbit by the electromagnetic attraction of the positive nucleus.

Answer:
The correct answer is option b. "streamlined bodies in dolphins and ichthyosaurs".
