Answer:
d. 4 yards of textiles.
Explanation:
In India, the ratio of yards of textiles to bushels of wheat that can be manufactured in one day's labor is given by:
[tex]r=\frac{12\ yards}{3\ bushels}\\r=\frac{4\ yards}{1\ bushels}[/tex]
This means that for each bushel of wheat, 4 yards of textiles could have been produced.
Therefore, the opportunity cost of one bushel of wheat in India is d. 4 yards of textiles.
