The correct answer is option B, that is, covalent bonds.
Covalent bonds are more prevalent in organic chemistry in comparison to ionic bonds. A covalent bond comprises of the concurrent attraction of two nuclei for one or more electron pairs. The electrons situated between the two nuclei are known as bonding electrons.
Covalent bonds take place between different atoms or similar atoms whose difference in electronegativity is not enough to permit the transfer of electrons to produce ions. The covalent bond is demonstrated by either as a solid line or long dash or as a pair of dots.

Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.
