I believe the answer is:
C. within 30 minutes
30 minute is the average time needed by human body to start lowering the amount of blood alcohol inside it. Consuming another alcohol below 30 minutes time frame would only accumulate the Blood Alcohol level and make you much more likely to experience the negative effect of alcohol.
flexibility is the component that is not skill related fitness
The body already produces enough protein to get by just fine. However, many people think athletes "use up" too much protein and faster than they gain it back, but that is not true because the body regulates homeostasis. I hope I helped :)
