Concept:We need to arrange the five given words so that the sentence becomes grammatically correct and meaningful.
Explanation:The intended correct sentence is: "I am having a big party next week at my house and I am inviting all my close friends."
The word after "I am" must be a verb, so "having" (E) comes first.
Next, "a big" requires a noun; "party" (D) fits here.
Then "next week at my" needs a place; "house" (A) is correct.
After "and I am", we need another verb; "inviting" (C) is used.
Finally, "all my close" needs a plural noun; "friends" (B) completes the sentence.
Thus the order is E, D, A, C, B, which matches option C (EDACB).
Answer:EDACB
