In experiments to test apical dominance, researchers found that:

A. if the shoot tip is cut off and auxin is
applied, the axillary branch will grow.
B. if the shoot tip is cut off and treated with a
substance that inhibits auxin transport, the
axillary branch will grow.
C. if the shoot tip is cut off and cytokinins are
applied, the axillary branch will grow.
D. if the shoot tip is cut off and treated with
something that inhibits cytokinin transport, the
axillary branch will grow.
E. branching is enhanced by the movement
of auxin from the shoot tip toward the root.
