An amount of $ 2392 are withheld in a year. (Correct choice: A)
In this question we must determine the amount of money that is withheld in a year. By considering a year as a 52-week period, the total money to be withheld in a year is equal to the product of the weekly money that is withheld and the number of weeks in a year, that is to say:
C = (52 weeks) • (46 USD/WEEK)
C = 2392 USD
An amount of $ 2392 are withheld in a year.
Hence, A is the answer.
