Consider ΔQRS, with right ∠S and point T located at the midpoint of SQ. Suppose SQ=23.1 and QR=39.47. Points A, B, C, D, and E located on segment RS. Additionally, suppose we have SA=16.0; SB=16.3; SC=19.8; SD=23.9; and SE=31.9. Based on these segment lengths, which segment is parallel to QR?

A. TA

B. TB

C. TC

D. TD

E. TE
