Answer:
option D "The demand is unitary elastic."
Explanation:
Data provided:
At price, P1 = 3,000 units
Demand, D1 = $ 50
also,
at price P2 = $ 60
Demand, D2 = 2,500 units
Now,
the percentage change in price = 
or
the percentage change in price = 20%
and,
The percentage change in the quantity = 
or
The percentage change in the quantity = -20%
The elasticity in demand (Ed) is given as:
Ed = (Percentage change in quantity) / (Percentage change in price)
on substituting the values, we get
Ed = (-20%) / 20%
or
Ed = - 1
Here the negative sign depicts the inverse relation between the price and the demand.
hence, the correct answer is option D "The demand is unitary elastic."
