Answer:

It could be any of them.

Step-by-step explanation:

First off, It could be said that (2c-d)(2c-d) doesn't belong because it includes two subtractions signs and none of the others do.

Secondly, It could be said that (2c+d)(2c-d) doesn't belong because it includes one subtraction sign and one addition sign and none of the others do.

Thirdly, It could be said that (2c+d)(2c+d) doesn't belong because it includes two addition signs, and none of the others do.

Finally, it could be said that (c+d)(c+d) doesn't belong because it doesn't have a multiplying factor of 2 within the parentheses.

I hope this helps :)
