The word in the passage that is the key to understanding Ophelia's tone is: B. AFFRIGHTED.
<span> Ophelia: alas! my lord, i have been so affrighted.
This means that she got scared or frightened. Her fear originated from seeing Lord Hamlet disheveled. </span>
I would say B. C could also be an option, but I think B makes the most sense :)
