Solution

The correct option is A $2 - p r o p y l h e x - 1 - e n e$
Longest C chain containing C=C has 6 C as:
$6 C H_{3} - 5 C H_{2} - 4 C H_{2} - 3 C H_{2} - 2 C^{1} -^{'} -^{'} -^{'}$
Parent name: hex
functional group: ene
lowest locant number to double bond:1
Substituent position:2
Substituent name: propyl
Therefore the name is: 2-propylhex-1-ene. Option A is correct.
