Answer:
A. supply curve shifts to the left
Explanation:
An increase in the prices of inputs from $4 to $6 shows economic problems that include a reduction in capital stock, labor, and an increased unemployment rate. This can also give room for inflation.

Due to all the above mentioned reasons, the supply curve of both long run and short run supply curves shifts left.
