E is definitely wrong, those IPs are formatted weird!

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.

I remember that IPv6 addresses should be valid, so A seems correct with that format.

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.

I remember that Java Access Bridge is important for automating Java apps, but I'm not sure if it's always required with Java spy mode.

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.
