Show me the steps to solve If IRP holds and $1-$year US and New Zealand interest rates are respectively $i_{\text{u}\text{S}\text{s}}=2\%$ and $i_{NZD}=4\%$

$($annual compounding$),$ what is the expected change over the next year in the uss$/$NZD exchange rate?

a$.$ The USD is expected to depreciate by $2\%$

b$.$ The NZD is expected to depreciate by $2\%$

c$.$ The NZD is expected to appreciate by $2\%$

d$.$ The NZD is expected to depreciate by $6\%$
