Answer:
c.A methyl group consists of a carbon bonded to three hydrogen atoms.
Explanation:
A methyl group is a ramification of the carbon chain, that has only one carbon and three hydrogens (-CH₃). This group is nonpolar because the electronegativity of carbon and hydrogen are very close, and the bond must be nonpolar. This group has no charge because it's nonpolar and it hasn't unpaired electrons.
