• A) \(\int _ { x - 2 } ^ { x - 2 } \int _ { y - x - 1 } ^ { y - x - 1 } 1 d y d x = 4\)
• B) \(\int _ { y - 1 } ^ { y - 1 } \int _ { x - - y - 1 } ^ { x - y + 1 } 1 d x d y = 4\)
• C) \(\int _ { x = - 2 } ^ { x - 2 } \int _ { y - x - 1 } ^ { y - x - 1 } 1 d y d x = 8\)
• D) \(\int _ { y - 1 } ^ { y - 1 } \int _ { x - - y - 1 } ^ { x - y + 1 } 1 d x d y = 8\)
