Answer

Brief Explanations:

To determine the biological factor in mental illness development, we analyze each option:

  • Infections: Some infections (e.g., certain viral or bacterial infections) can impact the brain and contribute to mental health issues, making this a valid biological factor.
  • Left - handedness: There's no established direct link to mental illness development as a biological factor for causation.
  • Height - weight ratio: Primarily related to physical health (e.g., obesity - related issues) and not a direct biological factor in mental illness development.
  • Birth order in a family: This is a social - psychological factor related to family dynamics, not a biological factor.

Answer:

A. infections
