$A .$ $\text{cis-3-hexene}$

#### Explanation:

$B .$ $\text{5-ethyldecane}$

For both molecules we find the LONGEST carbon chain. $B$ is trying to trick into identifying the sidechains as the longest chain: clearly the longest alkyl chain is $10 C$ long. In solution, so far as anyone knows, the organic chain twists and turns; when we draw the molecule we should assume the maximum symmetry possible; i.e. a straight chain.
