they can more easily play games in the back seats.
they can more comfortably have snacks in the back seat.

Explanation:

Airbags deploy with great force. Infants and young children are small and fragile. If they were in the front seat and an airbag deployed, the impact could cause severe injury. The other options (seeing outside, playing games, having snacks) are not safety - related reasons for placing infants and young children in rear seats.

Answer:

They can be severely injured from airbag impact.
