B. Plantar fasciitis

Explanation:

Plantar fasciitis occurs when the plantar fascia that joins your heel to your toes becomes swollen and painful as a result of constant straining. The plantar fascia, which has a web—like appearance, is very functional in providing support during movement  and also acts as shock absorber. Continuous straining of this thick ligament when involved in activities that puts much strain on it for long often results in the inflammation of the plantar fascia. Excessive running or walking, standing for long periods, wearing of inadequate shoes, and constant injury that strains the ligament are major causes.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
