Fimbriae also referred to as attachment pilus by some scientists is an appendage that can be found on both Gram-positive and Gram-negative bacteria, composed of helically arranged protein subunits. These appendages range from 3 to 10 nm to several micrometres.

C is correct.

Because fimbriae found in few gram positive & archaea.

As it said which bacteria may contain it's mean if they have few or more. Then the answer should be C.

It is found in gram -ve and some gram +ve.

I think the correct answer is C.

The answer should be B, because most gram-negative bacteria have fimbriae.

According to me, option B is correct.

Flagella present in G+ and G- bacteria.

Fimbriae present majority in G-bacteria. No/less in G+.

Yes, @Saurabh.

The fimbriae occur in gram - bacteria so I also think option B is correct.

No, @Stella.

Because many, not all gram+ bacteria have fimbriae but all grame- bacteria have fimbriae. That's why gram (-) was the better answer I think.
