C looks good to me, but I’m a bit confused about D with the commas. Is that allowed?

I’m not sure about B; I think the order of the hostname and IP might be off.

This seems straightforward to me. The user was in need of remediation, so the agent appearing in the notifications is the correct behavior. I'll go with option C.

This seems pretty straightforward. I think I'll use the textContent property to update the text value of the element.

Hmm, I'm a bit confused on whether we should recognize the $250,000 potential inflow or just disclose it. I'll need to review the accounting standards to make sure I get this right.
