Question on my practice exam

Well the choices are
A. Nucleus
B. Cell wall
C. Cell membrane
D. The capsule

The answer is A...and i don't konw if i'm just being dumb
but i thought bacteria don't have nucleus....and antibiotics are for bacteria only.

I thought antibiotics primarily target the cell wall or ribosomes (ribosomes not a choice though)

Can anyone tell me if this is right, or if there was a typo with the solution?

I'm doing this as a science project thats due tomorrow!!!! And... umm I swabbed areas of my house for bacteria to see which area had the most bacteria. I swabbed for samples Saturday, it is now Thursday. There are no signs of growth in the petri dishes. So... either I have a really clean house or I did something wrong.

A new specie laid 12 eggs. then died along with other creatures. The earth shook releasing the eggs to the suns rays. Then the eggs hatched and the chicks came out and fed from the ground, A rooster and 11 hens. wild breeding until fed were called chickens, well so much for the chicken and the egg theory.
