Solution

The correct option is C Iso has two $C H_{3}$ group and neo has three $C H_{3}$ on the C atom next to end C atom.
The terms $i s o$ and $n e o$ are used for branched-chain alkanes. In branched chain alkanes, if there is one $C H_{3}$ group on the C atom next to end C atom, then it is called isoalkane. If there are two $C H_{3}$ groups on C next to end C atom, then it is called neoalkane. If the structure is straight chain, it is called normal alkane.
