The correct answer is B.
Explanation:
All the molecules have the formula
However, B is not an isomer of hexane.
That structure is hexane.

All isomers of one compound must have the same chemical formula. So, if it doesn't have 6 carbons and 14 hydrogens, it's out. Unfortunately, they all are valid under that condition.
The only differentiating factor then, is whether it is a different atomic connection with respect to:
#"H"_3"C"-"CH"_2-"CH"_2-"CH"_2-"CH"_2-"CH"_3# which is the straight-chained structure.
(It technically is an isomer, but it is not an isomer of itself. Not the best-worded question.)
