Answer: C). the GDP deflator but not in the consumer price index.
Explanation:
GDP deflator is a measure of the prices of all the goods and services produced in a country. While, the CPI is a measure of only the goods that are purchased by the residents of a country. In addition to this, GDP deflator includes only goods produced domestically and not foreign goods. While, CPI includes prices of all the good that consumers buy including foreign goods.
Thus, a decrease in the price of domestically produced nuclear reactors will be reflected in the GDP deflator and not in the CPI.
