A New Drug Is Developed That Inhibits Formation of Flagella Filament

Multiple Choice

A new drug is developed that inhibits formation of flagella filament by impairing production of the protein flagellin. Is this going to be an effective medication?

A) Potentially yes-it could be used against some bacteria, but wouldn't be effective for those that don't use a flagellum to move around.
B) Potentially yes, but only if it could be shown that the drug also didn't impair the production of the eukaryotic flagellum.
C) Not at all-our eukaryotic cells depend on flagella to move around in our body, and this drug would impair that function.
D) Not at all-bacterial flagella are produced using microtubules, not the protein flagellin. This drug would be useless in eliminating bacteria.
E) Not at all-this medication would affect cells like the ciliated respiratory epithelial cells, and would cause potentially fatal side-effects.
