Solid gold. 10 carat indicates gold purity is not 100%. For 24 karat gold is pure gold.

I just took the test

It's C. because it 100% pure gold which makes it a pure substance

Unlike 10 karat gold in the corner, they are gold but with a high percentage of other metals being around 60% and the whole gold at 40%

So that would make C your answer!
