Given: C 2 _ X 2 C C _ X X 2 _ C 2 _ X _ C By checking options and substituting accordingly. 1) C2X2X → C 2 C X 2 C / C 2 X X 2 X / C 2 2 X X C 2) X2CX2 → C 2 X X 2 C / C 2 X X 2 C / C 2 X X 2 C 3) AXX2C → C 2 A X 2 C / C X X X 2 X / C 2 2 X C C 4) XCX2C → C 2 X X 2 C / C C X X 2 X / C 2 2 X C C Option (2) gives a cyclic pattern of C 2 X X 2 C / C 2 X X 2 C / C 2 X X 2 C Hence, ‘X2CX2’ is the correct answer.
