D. laid in his proposal

I guess it should be lay since we are speaking in general terms and not stating that "originality did the work of laying something in the past".

I am not sure though .
Can you post the OA??

You can not propose Fact....therefore, A, B and C out. E is out because of simple present tense. IMO D is correct

a,B and C out for wordiness

now D and E is a thing which need concept

first the part in his proposal contains an indirect object; saying that laid is a pst tense of lay which a transitive verb which req a direct obj , which is not the case here

however lay in E is psat tense of lie an intansitive verb which req an indirect obj which is exzctly the case here

some complex grammer
so E
