A) ​1.10 US dollars
B) 1 US dollar
C) 0.91 cents US
D) ​0.99 cents US

Therefore, the best choice is C, which states that a Canadian dollar is worth 0.91 cents in US dollars. Option A is incorrect because it implies that a Canadian dollar is worth more than a US dollar. Option B is incorrect because it assumes a 1:1 exchange rate, which is not the case. Option D is also incorrect because it implies that a Canadian dollar is worth less than one US cent, which is not the case.
