Step-by-Step Profession Assignment

To identify the three teachers, we must first determine the profession of all seven individuals by systematically applying the given clues. This is the same set of deductions as in the previous related puzzles.

1. Assigning Professions from Direct Clues

Several professions are given directly in the text:

• B is an Engineer.
• G is a Teacher.
• C is a Doctor.
• D is a Doctor.

2. Deducing the Remaining Professions

The professions remaining to be assigned are one Engineer and two Teachers. The people remaining are A, E, and F.

1. Clue (v): "A is not an engineer". Since the only other available profession is Teacher, A must be a Teacher.
2. Now, the remaining people {E, F} must be the last Engineer and the last Teacher.
3. Clue (vi) and (iv): "The pair of sisters A and F travel in the same vehicle" and "Two people from the same profession do not travel in the same vehicle."
4. Since A is a Teacher, and F is in the same vehicle as A, F cannot also be a Teacher. Therefore, F must take the only other available role, which is Engineer.
5. By elimination, the last person, E, must be the final Teacher.

Conclusion

After assigning all the professions, the three individuals who are teachers are:

• G
• E
• A

This group is represented by the option GEA.
