Option A is incorrect because the "rectangle" before "rectangleData" is not necessary and will result in a compilation error. 
Option B is incorrect because the parentheses after the struct name are not necessary and will also result in a compilation error. 
Option D is incorrect because the use of "new" implies dynamic memory allocation, but the struct is not a pointer type. 
Therefore, the correct option is C which declares a variable of the struct type "rectangleData" with the identifier "myRectangle".
