The text argues that if avocado growers in Mexico can produce avocados cheaper than avocado growers in the United States, this will not reduce total jobs available in the United States. The logic underlying this argument is that:
a) Mexico will export avocados to the United States, creating jobs in transportation and retail.
b) The United States will impose tariffs to protect domestic jobs.
c) Avocado growers in the United States will lower their prices to compete.
d) The total number of jobs is unrelated to trade.
