When we have to name an organic compound, one thing that we need to take into consideration is the type of bond that it is in the carbon chain. One way to determine what type of bond we have, is by counting the number of Carbons and Hydrogens present in the chain.
We know that we have 6 carbons
If we have 14 Hydrogens (6*2+2), we have an Alkane
If we have 12 Hydrogens (6*2), we have an Alkene
If we have 10 Hydrogens (6*2-2), we have an Alkyne
Since we have 6 carbons and 14 hydrogens, therefore we have an Alkane, option B
