Let W be the set of all vectors of the form shown on the right, where a, b, and c represent arbitrary real numbers. Find a set S of vectors that spans W or give an example or an explanation to show that W is not a vector space. 2a + 4b 7b + 5c 9c + 4a 5b Select the correct choice and fill in the answer box as needed to complete your choice. A. A spanning set is S = 0. (Use a comma to separate answers as needed.) There is no spanning set of W because W does not contain the zero vector. There is no spanning set of W because W is not closed under scalar multiplication. B. C. D. There is no spanning set of W because W is not closed under vector addition.
