D

Explanation: 

Detailed explanation-1: -All plants naturally possess hormones, including the growth hormone auxin, which is produced in immature parts of the plant, where growth is necessary. Synthetic auxins are used in hormone rooting powders and gels to replicate natural growth conditions in plants, and encourage roots to form.

Detailed explanation-2: -Chemicals known as auxins inform plants when to form roots. Rooting hormone products, which are commonly sold in powder, liquid, and gel form, contain natural auxins or synthetic compounds, which can be applied to clippings to stimulate root growth during propagation.

Detailed explanation-3: -The rooting hormone works on a variety of cuttings, including new growth, woody stems, leaves, and roots to dramatically increase the odds of success with propagation. If the plant is a blooming plant, wait until the blooms fade before taking the cutting.

Detailed explanation-4: -Depending on the rooting hormone product, rooting occurs usually after 2 to 8 weeks. Before this rooting period is over it usually isn’t necessary to water plants as often as they would normally need during the rooting stage under normal conditions.

Detailed explanation-5: -Rooting hormone products are chemicals that stimulate root growth, typically on plant cuttings. These synthetic commercial products mimic auxin, which is a natural plant hormone that stimulates root growth. Rooting hormone comes in powder, liquid, or gel form. You don’t need to use rooting hormone for cuttings.
