Alex, a software engineer, dedicates a considerable amount of his free time to developing free educational software for underprivileged children. This commitment does not align with the simple expectation of self-interest driven behavior from a sociobiological perspective. Which explanation best accounts for his behavior?

Sociobiology strictly predicts that individuals will only engage in activities that directly increase their personal wealth.

The development of free educational software does not contribute to societal well-being and, therefore, cannot be explained by sociobiology.

Engaging in altruistic acts like creating free educational software can increase an individual's social reputation, potentially benefiting their genetic fitness indirectly.

Sociobiology claims that modern humans are entirely motivated by the desire to spread their genes, making any other form of behavior inexplicable.
