The colon operator is used to generate a numeric sequence. In this case, starting from 2 and skipping every other number until 20. Therefore, option B is the correct way to generate the set of even numbers. Option A is not correct as it generates a vector with three elements (2, 2, and 20). Option C is not correct as it generates a vector with only two elements (2 and 20) and does not include even numbers in between. Option D is not correct as it generates a vector with three elements (2, 20, and 2) and does not include even numbers in between.
