A
1, 1, 1-trimethyl-2-propene
B
3, 3, 3-trimethyl-2-propene
C
2, 2-dimethyl -3-butene

Answer

3, 3-Dimethyl-1-butene

Explanation:

The IUPAC name of (CH₃)₃C−CH=CH₂is 3, 3-dimethyl-1-butene.

The parent hydrocarbon contains 4 C atoms and a C=C double bond.

Hence, it is a butene. Two methyl groups are present as substituents on third C atom. Prefix di indicates two methyl groups.
