A, and C are correct, And yes, you can replace "except" with "except for." As for B, I would recommend changing it to be, "Even though everyone presented at the meeting, he agreed to my proposal." Hope this helped!

I agree with Jerome and Nora, except for D. I believe you were correct to use "was", as the subject of the sentence is "no one", which is singular. Another way to order the sentence is: Except for their near friends and close relatives, no one was invited to their wedding. I hope this helps!

a. When I explained my proposal, everyone present at the meeting agreed to it, except him. (I think "except for him" is also okay here. Am I right?) b. When I explained my proposal, everyone present at the meeting, but he, agreed to it. c. No one was invited to their wedding except their near relatives and close friends. (I think "except for" is also okay, but need confirmation.) d. No one but their near relatives and close friends were invited to their wedding. a. correct b. present. Note the use of the commas before but and after he. c. correct d. were instead of was
