Answer:
b. An individual demand for an item will decrease causing a downward slope.
Explanation:
The law of demand states that when other factors are held constant, the price and demand have inverse relationship, which means that as one increases, the other one decreases. So in the case of the of your problem, as the price of an item increases, the demand will decrease (the opposite would be true as well).
So when you put it in a graph, the demand curve would be sloping downwards.
