Which of the following statement is true according to the given arrangement?

We are given that G is 5th to the left of C. There are only 2 cases possible:

Case 1: _ G _ _ _ _ C. F is fifth to the right of A. This gives only 1 possibility:
A G _ _ _ F C. 
E is 2nd to the left of B. This also gives only 1 possibility:
A G E _ B F C and the remaining place is taken by D:
A G E D B F C. Reporter is 3rd to the right of G and engineer is 2nd to the left of D and doctor is to the immediate left of engineer.
A(doctor) G(engineer) E D B(reporter) F C. 
There are only 3 people between engineer and painter and the Lawyer is to the immediate right of the Teacher which is only possible when E is Teacher and D is the Lawyer.
The final arrangement will look like:
A(doctor) G(engineer) E(Teacher) D(Lawyer) B(reporter) F(painter) C(actor).

Case 2:  G _ _ _ _ C_. F is fifth to the right of A. This gives only 1 possibility:
G A _ _ _ C F.
E is 2nd to the left of B. This also gives only 1 possibility:
G A E _ B C F and the remaining place is taken by D:
G A E D B C F. Reporter is 3rd to the right of G and engineer is 2nd to the left of D and doctor is to the immediate left of engineer.
G(doctor) A(engineer) E D(reporter) B F C.
There are only 3 people between engineer and painter which means that F will be the painter and the Lawyer is to the immediate right of the Teacher which is not possible in this arrangement. 
Thus, Case 2 is invalidated and the only final arrangement is :
A(doctor) - G(engineer) - E(Teacher) - D(Lawyer) - B(reporter) - F(painter) - C(actor).

According to the arrangement, only Option D is correct i.e. Lawyer is standing in the exact middle.
