Hello Student
Correct answer is 1. Auxin in apical part of shoot have the ability to bans part the cytokinin from root in the apical of shoot.
In the apical part of shoot whin the cells divide actively auxin transport the cytokinin towards the apical part so that it is not transported towards the axillary bud if cytokinin transported towards axillary bud or sprayrd on the plant axillary bud starts dividing from the shoot this shows that auxin to cause apical dominance cytokinin should be transported into apical.
