The main function of auxin is to help plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant is one of the main places that auxin is produced.

Answer:
Introduction:
Auxins are a type of plant hormone that plays a crucial role in the growth and development of plants. They are primarily synthesized in the apical meristem, which is the growing tip of the plant. Auxins are responsible for several functions in plants, including cell enlargement, root formation, apical dominance, and phototropism.
Explanation:
Let's go through each option and determine whether it is a function of auxins or not:
A. Cell Enlargement:
Auxins promote cell enlargement by increasing the plasticity of the cell wall, allowing it to stretch and accommodate the growth of the cell. This is an important function of auxins and aids in the overall growth and development of the plant.
B. Induces Dormancy:
This option is incorrect. Auxins do not induce dormancy in plants. Dormancy is regulated by other hormones such as abscisic acid (ABA). ABA promotes dormancy by inhibiting the growth of plant tissues and promoting the formation of bud scales.
C. Root Formation:
Auxins promote root formation in plants. They are responsible for the initiation and development of roots from stem cuttings. Auxins stimulate cell division and elongation in the root meristem, leading to the formation of new roots.
D. Overcome Apical Dominance:
Auxins are involved in the regulation of apical dominance. Apical dominance is the phenomenon where the apical bud inhibits the growth of lateral buds. Auxins produced by the apical bud suppress the growth of lateral buds, allowing the apical bud to grow uninhibited. When the apical bud is removed or damaged, the auxin concentration decreases, and lateral buds are released from their dormancy, resulting in the growth of lateral branches.
Conclusion:
Based on the above analysis, the correct answer is option B. Auxins do not induce dormancy in plants, and root formation and overcoming apical dominance are both functions of auxins.
