Correct Answer
BPosition
CGeometrical
DOptical

Solution

$$H_3\underset{1}{C}-\overset{CH_3}{\overset{|}{\underset{2}{CH}}}-\underset{3}{CH_2}-\underset{4}{CH_3}$$
$$\underset{1}{CH_3}-\overset{CH_3}{\overset{|}{\underset{CH_3}{\underset{2|}{C}}}}-\underset{3}{CH_3}$$
Both isomers have different carbon chain
