Correct option is C
Option 1 is correct: Health outcomes in individuals are determined by a combination of genetic predisposition and environmental exposures such as nutrition, sanitation, lifestyle, and infections.
Option 2 is also correct: These genetic and environmental factors do not act in isolation; rather, they interact dynamically. For example:
Good nutrition may promote health even in genetically vulnerable individuals.
Poor environmental conditions can trigger disease in genetically susceptible populations.
Such interactions may be beneficial (health-promoting) or harmful (disease-causing).
Thus, both Option 1 and Option 2 are correct → Option (c).
