Answer:

The correct answer is option B, that is, they contract very quickly.

Explanation:

The fast-twitch muscle fibers vary from the slow-twitch muscle fibers as they possess the tendency to generate energy in the non-presence of oxygen. This permits them to generate energy briskly by utilizing glycogen and phosphocreatine, to fuel those brisk explosive motions like sprinting and jumping.  

This signifies that the fast-twitch muscle fibers exhibit faster contraction speeds in comparison to the slow-twitch muscle fibers. The fast-twitch muscle fibers are further differentiated into two types. The slow-twitch muscles assist in performing long-endurance activities like distance running, while the fast-twitch muscle fibers are utilized in performing powerful spurts of movements.

Ok so I had a pumpkin spice frappucino and now my farts smell really bad and I hope this is normal.
seraphim [82]
I dont have a "scientific" answer for that but I'm pretty sure is it normal :). 
Maybe everything in that frappucino such as the milk, cream, flavoring just makes it smell bad.
