I eliminated BDE quickly, but really got confused while facing the choice between A and C.
I thought they have differnt meanings so I went for A. Do "in that they will jointly adopt" in A and "by jointly adopting" in C have the same meaning?
The "they" in A might be obscure, but I got a sentence, which I thought was where this question come from, from the New York Times:
Thirteen states from all regions of the country will try to impose new national controls on pollution from truck and bus engines on Monday, when they announce a plan to jointly adopt emission limits that would be far stricter than the federal rules.
There was a "they" there. Was it a bad usage that lead to obscure indication?
