The correct answer is C. Financer.
A financier is a person who manages money, especially for a business or government. The word financier comes from the French word financier, which means "to finance."
The other options are incorrect because they are not spelled correctly. Option A, Finnancer, is missing the "i" in the middle. Option B, Financier, is missing the "e" at the end. Option D, Financeir, is spelled in Portuguese.
