The right answer is spiral.
Size and shape vary from one bacterium to another. The majority of bacteria have a size between 0.5-5 μm in diameter.
Most bacteria are either spherical or rod-shaped. In the first case they are called cocci (of the Greek kókkos, grain) and in the second bacilli (of Latin baculus, rod). There are also intermediate forms: coccobacilli. Some rod-shaped bacteria are slightly curved like vibrio. Other bacteria are helicoidal. They are spiral if the form is invariable and rigid, spirochaetes if the body is flexible and can change shape.
