Final answer:
VO2 max value is influenced primarily by training status and effort during testing, but genetic factors, age, and gender also play essential roles.
Step-by-step explanation:
The final VO2 max value is influenced by several factors, most notably by training status and effort during testing. However, the choices that can influence VO2 max certainly include a broader range of factors. A person's genetic factors and age can play a significant role in determining their baseline VO2 max as well as the potential for improvement. Similarly, gender has been found to affect VO2 max values, primarily due to physiological differences between males and females. In addition, the extent of an individual's physical training and the effort they exert during a VO2 max test will significantly affect the outcome. Therefore, the appropriate answer to the student's question is c) Training status and effort during testing, although it is important to acknowledge that genetic factors, age, and gender can also influence VO2 max.
