When classifying, they ask me if bars of prohibition appear in the center of the galaxy and I do not understand what it refers to, can they explain me?

Sorry I should have explained better, my question does not refer to the image of the galaxy, it refers to the message when classifying a galaxy

Is there any sign of a bar feature through the center the galaxy?/ X BAR NO BAR

You can click on the Examples button to see barred galaxies.
A bar is a straight line of stars on each side of the nucleus, see SBa SBb and SBc
Here is a picture of a bar in a spiral. Most bars are harder to see than this one.
