Answer:
C. Beer and Marijuana are complementary goods
Explanation:
Since an increase in the price of beer is reducing the demand for marijuana this means that people were buying both at a time, now that the price of beer is higher they cannot afford both so are buying beer only. Therefore we can say that Beer and Marijuana are complementary goods.
If the increase in beer price led to an increase in Marijuana demand, then that would make them substitute goods since people are <u><em>substituting</em></u> one vice for another cheaper one.

This phenomenon is called social facilitation. 
Explanation:
Social facilitation refers to one's <em>tendency to </em><em>improve</em> his/her performance <em>when other individuals are present</em>. When the individual is alone, he/she has certain performance but having other individuals around tends to make this individual want to improve. 
In this case, Cody is riding the bike at a leisurely pace but as soon as the gym gets less empty, she <em>improves her performance by the sheer presence of others. </em>
