I feel like option C might work, but I can't recall if the `\s` is the right choice for what we need here.

None of these seem quite right to me. I thought we needed to use something like `(\w+)` for just the hostname.

I remember practicing regex questions, and I feel like we need to focus on the part before the first dot.

I think option A looks familiar, but I'm not sure if it captures just the hostname correctly.

Okay, I've got it! The answer is C. The (.*) will capture the hostname, and \s will match the whitespace after it. Nice and simple.

Hmm, this is a tricky one. I'm leaning towards option B, but I'm not 100% sure. I'll double-check the regex syntax to make sure I'm understanding it correctly.

I'm a bit confused by this question. The regex expressions all look pretty complex to me. I'll have to think it through carefully.

I think the answer is C. The regex (.*) will capture the hostname, and \s will match the whitespace after it.

I think D) The server (.*?)\\* is too restrictive and won't capture the full hostname

I think option C is the correct regex expression. It captures the hostname (webserver3) between 'The server' and '.domain.com'.
