Answer: C) $1.04/C$1
Explanation:
We define the inflation rate in a certain country as
1 year ago the spot rate of U.S. dollars for Canadian dollars was $1/C$1.
That time inflation rate in US was 4% greater than in Canada.
So, the current spot exchange rate of U.S. dollars for Canadian dollars :
($1 + 4% of $1)/C$1
=($1+$0.04)/ C$1
=$1.04 / C$1
Hence, the correct option is C) $1.04/C$1
