Answer:
The correct answer is option C.
Explanation:
Suppose tea and coffee are substitutes. Now, unfavorable weather adversely affects coffee production leading to an increase in the price of coffee. This increase in coffee price will lead to a decline in the quantity demanded.
Since tea is a substitute for coffee and people will prefer the cheaper substitute, the demand for tea, as a result, will increase. This will cause the demand curve for tea to shift to the right.
