Ana, Bento, and Lucas participate in a contest consisting of 20 questions, with the following rules.

- Each correct answer is worth 5 points.
- Each wrong answer results in a loss of 3 points.
- Each unanswered question results in a loss of 2 points.

|  | correct | wrong | unanswered |
| :--- | :---: | :---: | :---: |
| Ana | 12 | 3 | 5 |
| Bento | 13 | 7 | 0 |
| Lucas | 12 | 4 | 4 |

Using the contest results from the table and writing the names of the three in descending order of ranking in the contest, we get:
(a) Ana, Bento, Lucas;
(c) Ana, Lucas, Bento;
(e) Bento, Ana, Lucas.
(b) Lucas, Bento, Ana;
(d) Lucas, Ana, Bento.
The correct option is (e).

From the table, we obtain the number of points for each of the three participants.

$$
\begin{aligned}
& \text { Ana: } 5 \times 12+(-3) \times 3+(-2) \times 5=60-9-10=41 \\
& \text { Bento: } 5 \times 13+(-3) \times 7+(-2) \times 0=65-21=44 \\
& \text { Lucas: } 5 \times 12+(-3) \times 4+(-2) \times 4=60-12-8=40
\end{aligned}
$$

Therefore, Bento was the best ranked, followed by Ana and then Lucas.
