What happens to black holes in the Heat Death scenario?

• They grow indefinitely by absorbing all matter.

• They slowly degenerate and evaporate due to Hawking radiation.

• They merge to form a single supermassive black hole.

• They remain stable and unchanged.

What would cause the universe's expansion to slow down, stop, and then reverse in the Big Crunch scenario?
