The answer is C, the strings. The strings are defined as "singing" which is something strings can't do, but a peoples can. Hope this helps. <span />
It's alright..
Sharks are everywhere including the sand so everyone could pretty much be walking on sand sharks. A bull shark won't gobble you up the most damaging it could do is bite your legs and/or arms. Just be sure to swim in the shallow close to the sand. If you see otters or any sea creatures it means a shark could be nearby so be sure to stay really close to shore. Also sharks could be in the shallow as well, just be sure to wear a life jacket & stay by an adult always. Be sure your not bleeding anywhere so that it doesn't attract the sharks. Also don't worry, I truly believe that your gonna be okay.
Final thing, if you see a fin or any strange movement in the water just be sure to get to shore in case. I have a phobia of the ocean and sharks as well.. but don't worry we both could conquer our fears like I went on bigger roller coasters that were fast and I've always been afraid of those, but I'm still scared of them as well. Just know that no matter what people will always be with you even to help you.
