The correct option is B J

On the basis of the given information, we can tabulate that:-
$\begin{array}{ccc}A& E& G\Rightarrow Doctors\\ D& H& J\Rightarrow Lawyers\\ B& I& \Rightarrow Engineers\\ C& F& \Rightarrow Managers\end{array}$
It is also inferred that - Every team must have persons of each of the professions. Therefore, one team will have a manager, an engineer, two lawyers and a doctor and the other team will have a manager, an engineer, a lawyer and two doctors, such as:-
$\begin{array}{ccc}Iteam& IIteam& Profession\\ A& E,G& Doctor\\ H,J& D& Lawyer\\ F& C& Manager\end{array}$
