Are bonds in which valence electrons are shared.
a. ionic bonds
b. atomic bonds
c. covalent bonds eliminate
d. hydrogen bonds

 C. Covalent bonds

Explanation: The bond between the 2 atoms can be formed by either sharing the electrons or by donating the electrons or by the method which fall under other types.

Thus when we talk about the sharing of electrons, there will be the formation of the Covalent Bonds. Covalent Bonds are the bonds which are formed by the sharing of electrons between 2 atoms in order to complete each others' octet.

Ionic bonds are the bonds which are formed by the transferring of electrons from one atom to the other one to complete octet.

Hydrogen bonds are the bonds which are formed by the electrostatic forces of attraction between the electronegative atom of the one species and acidic hydrogen of the another one.
