I$\text{'}$m asking you pick the option which is most correct, shouldn't be that hard to understand how a multi$-$choice question works considering you're "experts." Trying again for the third time: The exchange rate for a currency depends on many factors, including:

a$.$

the rate at which the New Zealand currency is pegged, relative to the other currency of interest.

b$.$

the price of McDonald's hamburgers in each country.

c$.$

the price of options on futures of the foreign currency.

d$.$

the demand for and supply of the currency in the market.
