Answer:
The correct answer is option b.
Explanation:
A budget line shows the maximum possible combination of two goods that a consumer can purchase by spending his/her whole income.
The quantities of those two goods are mentioned on both the axes. If the price of both the products is doubled. The consumer will be able to afford half the quantity than what he was consuming earlier.
This will cause the budget line to shift to the left. This new budget line will be parallel to the initial one. The slope of the budget line will remain the same.
