Constutuional Isomers are also called Structural isomers. The constitutional isomer is a form of isomers in which molecues with the same molecular formula have different bonding pattern and atomic organisation.
As we can see in the given options for hexane only option-b and option-c have same molecular formual(C6H8) but different bonding pattern and atomic organisation. So, are only tow constitutional isomers of hexane here (b) and (c)
