I have a doubt regarding option C, why is that choice wrong? Can you please explain.
Here is the sentence using choice (C):
"Not one of the potential investors is expected to make an offer to buy First Interstate Bank until a merger agreement be signed by them with a provision for penalties if the deal were not to be concluded."
The pronoun "them" is ambiguous... who will sign the merger agreement? The bank itself is singular, so the only possible referent in this sentence is the
potential investors, but it probably doesn't make sense for all
potential investors to sign any sort of agreement. Is the agreement to be signed by executives of First Interstate Bank? Shareholders? Board members? If those people aren't explicitly mentioned in the sentence, "them" can't refer to any of them.
Also, the use of the subjunctive "be signed" is not necessary in this case. For example, you would say, "I will not eat my soup until the fly is removed", not "I will not eat my soup until the fly be removed."
You could, however, use the subjunctive to express a hope/request/demand. For example, "I demand that the fly be removed from my soup."
I hope this helps!
