Answer:no marlow isn't eavesdropping
Explanation:he isn't eavesdropping bc they walked under him and just thought they were in private so they should've looked better and he was there first not saying he should be petty about it but it would make marlow a better person by letting them know so after they finish talking they don't spot him and then accuse him of eavesdropping.
I believe that A could be correct. The problem with C is that comma. Again, I'm not sure. You should wait for another person to help also. (I'm better at math.. Not English)
<em>I hope this helps!~
I will find someone else to help! :)</em>
the answer would be the second answer
