positive chemotaxis is the correct answer.

Explanation:

Chemotaxis is a response where cells show their migration as per the several chemicals in their surroundings.

formyl peptides and chemokines are examples of chemotactic factors that stimulate the movement.

Example of chemotaxis is the migration of the immune cells in the direction of chemoattractants released by the infected or injured cells.

Positive chemotaxis is the migration of cells towards the higher concentration of chemicals.

Negative chemotaxis is the movement of the cells towards a low concentration of the chemical.
