C: Performance reports are mainly in the Performance tab, not the console.

D: Yes. You can alter the DOM and redefine or override JS functions/variables at runtime.

I think options B and D are correct since we can manipulate the DOM and maybe even the JavaScript code, but I'm a bit confused about option A.

I remember practicing with similar questions, and I believe we can run code that's related to the page, but not sure about unrelated code.
