Since you know that $\mathbb{R}_l$ is totally disconneted and since $\mathbb R$ is connected, then you now that the answer to (b) is: only the constant functions.

On the other hand, since $\mathbb{R}_l$ is totally disconnected, its only connected non-empty subsets are the singletons. And this implies that its only path-connected non-empty subsets are the singletons too.
