To choose the correct demonstrative adjective for the blue race car in the picture, you should consider the following:
- Gender: "car" (carro in Spanish) is masculine.
- Proximity: Since the blue car is the one closest to you, you would use the demonstrative adjective that indicates "this" (closest).
Therefore, the correct choice for the blue race car (masculine singular) that is closest to you would be "este".
So the answer is este.
