Answer:
Louis ventures into the field of growing sugarcane to have good quality raw materials for his sugar factory, and have less dependence on the suppliers.
Step-by-step explanation:
Backward integration is the process in which an organization acquires a company that supplies the raw material that it uses to manufacture its products. This is a type of vertical integration that allows an organization to guarantee the availability of the raw material it needs.
According to this, the sentence that shows that the company is using backward integration is: Louis ventures into the field of growing sugarcane to have good quality raw materials for his sugar factory, and have less dependence on the suppliers as he got into this to produce the raw material he needs to produce sugar.
