Verified by Experts

The correct Answer is:
A
`C_(5)H_(12): underset("n-Pentane")(CH_(3)CH_(2)CH_(2)CH_(2)CH_(3))`
`underset("2-Methylbutane (iso-Pentane)")(CH_(3)-underset(CH_(3))underset(|)(C)H-CH_(2)-CH_(3))" "underset("2,2-Dimethylpropane (neo-Pentane)")(CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(3))`
