A) Subjects tend to be vividly but disturbingly portrayed in Egon Schiele's portraits, often his closest friends and relatives.'Subjects" are portrayed, so here "often" is modifying "portraits", incorrect.

B) Subjects tend to be vividly but disturbingly portrayed in Egon Schiele's portraits, who were often his closest friends and relatives.Again "who" wrongly modifies portraits, incorrect

C) Subjects of Egon Schiele's portraits, often his closest friends and relatives, tend to vividly but
disturbingly portrayed. Here "tend" incorrectly modifies "subjects", incorrect

D) In Egon Schiele's portraits, the subjects, often his closest friends and relatives, tend to be vividly but disturbingly portrayed. Yes, makes sense. look at this"the subjects" often his relatives, tend to be adcd portryed. Correct

E) Vividly but disturbingly, the subjects portrayed in Egon Schiele's portraits tended to be his closest friends and relatives.Incorrect, "tended" is wrong, awkward construction.

The OA is D.
Please note the pronoun 'his'. 'His' clearly wants to refer to Egon Scheile. However, the antecedent is Egon Scheie's portraits. Is the usage of pronoun 'his' correct here? As I have read, a pronoun cannot refer to a modifier.

Please help.
