What is the molecular formula for the below line-angle structure?

The structure is a pentagon with one line connected to a corner. I'm sorry if that doesn't make any sense but the picture will not paste here.

a C6H11
b C5H11
c C7H12
d C5H13
e C6H12

Thank you so much in advance!!

To determine the molecular formula for the given line-angle structure, you need to count the number of carbon and hydrogen atoms in the molecule.

Counting the carbon atoms:
In a pentagon, each corner represents a carbon atom, so there are 5 carbon atoms in the structure.

Counting the hydrogen atoms:
Each carbon atom in an organic compound is bonded to either one or two hydrogen atoms, depending on the presence or absence of a double bond. In this structure, the carbon atoms are bonded to a total of 11 hydrogen atoms.

Therefore, the molecular formula for the given line-angle structure is C5H11, which corresponds to option b.
