How do motile bacteria move towards a nutrient?
Bacteria movement is entirely random, so they are equally likely to move toward and away from a nutrient
Fimbriae cause bacteria to tumble in a counterclockwise direction toward particular chemicals
The glycocalyx allows bacteria to move in a straight line
Bacteria perform only negative chemotaxis
Flagella rotations propel bacteria toward a chemical attractant

Solution
Bacteria movement is random,. motile bacteria can sense nutrient and they will move towards nutrient by the process of chemotaxis and similarly, they will move away from the harmful substances. So the correct option will be the first one that BActeria movement is entirely random, so they are equally likely to move towardand awaqy from a nutrient.
