To function properly,children's safety

seats and restraints must:

1. be installed correctly and anchored
to the vehicle.

2. face the back of the seat.

3. come with a lap belt and shoulder
harness.

Would number 1 be the best answer?

My text says:
"Safety seats and restraints must not only be appropriate,but also installed
and used correctly to protect young children: they must be correctly installed(facing the front or back as
is appropriate) and anchored in the vehicle."

Number 1 is the correct answer.

Number 2 is correct only if number 1 has been seen to and the child weighs less than 20 pounds.

Number 3 is correct only if number 1 has been seen to.
