Answer: B. A covalent bond in which the electrons are shared equally

Explanation:

Covalent bonds are formed by sharing of electrons between non metals.

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the unequal sharing of electrons between the atoms. Example: $HF$

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms. It is also defined as the bond which is formed due to the equal sharing of electrons between the atoms. Example: $H_2$

B. A covalent bond in which the electrons are shared equally .

A. "A covalent bond in which the electrons are shared unequally" is incorrect. Such a bond would be a polar covalent bond

C. "A covalent bond formed between a metal and a non-metal" is incorrect. Such a bond would be an ionic bond.

D. "A covalent bond formed between two different elements" is incorrect. We would need to know the elements before we could decide the type of bond.

1. Coherence Theory (Theory of Coherence)

Based on this theory, a knowledge considered to be true if the knowledge kehoren with the knowledge that exists and has been proven to be true. In the study of mathematics this is usually called the deductive nature.

2. Correspondence Theory (Theory of corespondence)

Based on this theory, a knowledge considered to be true if the knowledge of having a relationship with a reality that is true. This theory is based on the empirical fact that knowledge is true if there are facts that support that is true knowledge. Thus the truth here is based on inductive inference.

3. Pragmatic Theory (Theory of Pragmatism)

According to this theory, knowledge is said to be true if the knowledge is seen practically completely or have properties that true practicality. Followers of this theory argue that knowledge is true if it has keguanaan practical.
