for (c), i do not see how a rectangle ABCD can be formed because in naming figures we usually label either in the clockwise or anti-clockwise direction. Following that rule i dont see how ABCD can be a rectangle regardless of where D is placed. A parallelogram can be formed yes but not a rectangle. The only way to form a rectangle with D being at the coordinates stated in my answer. So either theres an error with the question or i am missing something here

if i am missing something and someone else knows an answer the fits the question than please do let us know. thank you :)
