Final answer:
Option b) 'Time management' is not one of the three main causes of foodborne illness, which are poor personal hygiene, cross-contamination, and temperature abuse.
Step-by-step explanation:
The question asks which option is not one of the three main causes of foodborne illness. Foodborne illness, or food poisoning, often results from improper handling, preparation, and storage of food. The main causes of food contamination and subsequent illness include poor personal hygiene, cross-contamination, and temperature abuse. Poor personal hygiene can lead to the spread of microorganisms like norovirus, which is a leading cause of foodborne disease. Cross-contamination occurs when food becomes contaminated by microbes from another food item, either directly or indirectly. And temperature abuse happens when food is kept at temperatures that allow bacteria to grow.
Considering these main causes, option b) 'Time management' is not one of the three main causes of foodborne illness. Time management could be related to temperature control because food that is left out too long at room temperature could lead to bacterial growth; however, it is not classified as one of the primary causes of foodborne illness in the context of the provided options.
