I think by far the best bang for your buck to save the most people is to identify as many as possible an develop technologies to deflect big ones. Detection of most of the large ones has already happened. Start big and work your way to the smaller ones.

Not sure how many people can fit into a underwater city. Likely be an extremely high Cost per person.

Before I click the link the following obligatory reply is needed:

It originated from Klendathu, deep in the Arachnid quarantine zone right?

The results suggest the meteor belongs to a well known family of space rocks - known as the Apollo asteroids - that cross Earth's orbit.

Of about 9,700 near-Earth asteroids discovered so far, about 5,200 are thought to be Apollos.

We need more guns and bombs and planes to defend ourselves from these Apollo asteroids.
