Correct answer: D

I follows: engineers say the bridge may be unsafe, and people's lives are at risk. Closing it until repair is strong but proportionate to that danger.
II follows: once the bridge is closed, passengers still need to cross, and sending them to the other footbridge is practical.
Both I and II follow.

Worth noting

A closure looks extreme, which is the trap. When the problem is a danger to life, a temporary closure is the proportionate step.

Concept: A strong step can be proportionate to a serious problem
