In autotrophs, water is transported through:(a) root hair (b) phloem (c) stomata (d) xylem

Academic Biology NCERT Class 10

(d) xylem

Xylem is a vascular tissue in plants, which helps in the translocation of water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
