the OA is B but My questions are the Following:
1)-Is not "including" a present participle that should make sense with the subject and the verb of the anterior sentence which is "Curators" and as a consequence this sentence convey the sens that the curators include photographs and diagrams?
2)- Is not the "their most famous bridges" quite ambiguious as their may refer to the swiss designers as well as to the curators?
Many thanks in advance

INCORRECT; "their contribution" should not be describing Curators rather "Swiss" must be included

C) In Order To Document The Contribution Ofthe Swiss To The Field Of Structural Engineering, The Curators At The University's Art Museum Organized A Comprehensive Exhibition Of The Work Of Leading Swiss Designers, Including Photographs, Diaphrams, And Models Of Its Most Famous Bridges And Buildings
INCORRECT; we need plural pronoun

D) In Order To Document Their Contribution To The Structural Engineering Field, A Comprehensive Exhibition Was Organized By The Curators At The University's Art Museum Of Their Photographs, Diaphrams, And Models Of Their Most Famous Bridges And Buildings
INCORRECT; "their contribution" should not be describing Curators rather "Swiss" must be included

thanks for your quick reply
but my questions indeed are targeted to the OA itself.
I think that including used this way is wrong, it means that that curators include themselves diagrams etc and the last their doesn't have a clear antecedent
Did you get my point?
