Final answer:
The bond formed between carbon and selenium is considered nonpolar covalent.
Step-by-step explanation:
A polar covalent bond is formed when there is an unequal sharing of electrons between atoms. To determine if a bond is polar covalent, we compare the electronegativity values of the atoms involved. In this case, the electronegativity difference between carbon (EN = 2.5) and selenium (EN = 2.4) is very small (0.1).
Therefore, the bond formed between carbon and selenium is considered nonpolar covalent.
