The correct answer is (B) Group 18 elements are unreactive because they have a complete outermost shell of electrons. Group 18 elements have a stable configuration of eight electrons in their outermost shell, which makes them very unreactive and inert. They do not readily form chemical bonds with other elements. Hence option B is the correct answer.

Option (A) is incorrect because Group 18 elements are unreactive due to their complete outermost shell of electrons, not an incomplete outermost shell. Hence option A is incorrect

Option (C) is incorrect because Group 18 elements are generally unreactive with both metals and nonmetals. Hence option C is incorrect.

Option (D) is incorrect because Group 18 elements are generally unreactive with both metals and nonmetals.  Hence option D is incorrect.
