Correct option is B, PIN. In Auxin Phytohormone problems like this, the accurate statement is PIN; the others are common mix-ups. Not these: A) AUX/LAX; C) TAA; D) ARF. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.

Go with C — AUX1. Under Auxin Phytohormone, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) PIN; B) ABCB; D) YUCCA. When two options sound similar, choose the one that matches the textbook definition most tightly.

Toward base (B) is correct here. This is core Auxin Phytohormone: once you know the definition or pathway step, Toward base is the clear fit. The wrong ones are A) Toward apex; C) Radially; D) Laterally. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.
