In a mathematics competition, $A, B, C, D, E$ and $F$ participated. After the first test, the organizer said: "3 contestants have 10 points, the others have 7. Everyone should submit their guess about who they think earned 10 points." The contestants submitted the following guesses:

$$
A, B, D ; \quad A, C, E ; \quad A, D, E ; \quad B, C, E ; \quad B, D, E ; \quad C, D, E
$$

The organizer announced that no one guessed all three qualifiers correctly, 3 guesses got 2 right, 2 guesses got 1 right, and 1 guess got none right.

Based on this, who had 10 points?
