Correct answer: B. Make it grow out
Explanation: Cytokinin counteracts the auxin from the shoot tip, releasing the lateral bud from apical dominance so it grows.
Geometric growth (where both daughter cells keep dividing) produces this classic S-shaped curve: a slow lag phase, a rapid exponential phase, and a levelling-off stationary phase as nutrients or space become limiting - the same fundamental pattern seen in population growth.
