The correct option is B

  2. This is possible due to the proton motive force generated which results in the clockwise or anticlockwise motion of the flagella.
  3. This is how motile bacteria can move by moving in a direction or stumbling in the same place.

Explanation of the incorrect options:

Option A:

  1. Fimbriae are long filamentous polymeric protein structures located at the surface of bacterial cells.
  2. They enable the bacteria to bind to specific receptor structures and thereby colonize specific surfaces.

Option C:

  1. Cilia is a locomotive organ present in eukaryotes.
  2. They are present in various tracts like the fallopian tubes and the respiratory tract.

Option D:

  1. Pili is a hair-like outgrowth in bacteria.
