T is a one-to-one transformation from Rto R A. For every x in R, there is a y in R such that T(x) = y. B. For every y in R, there is a x in R such that T(2) = y. C. For every y in R, there is a unique z in R such that T(x) = y. D. For every y in R, there is at most one z in R such that T(2) = y. (Enter "A", "B", etc.; not "A.", "B.", etc.)
