To understand the scope of the business, competition, and communities.

• A. Study
• B. Products
• C. Commit
• D. Define

Answer: (A)

Studying is the act of examining and learning about something in depth. To understand the scope of the business, competition, and communities, you study those areas to gain insights into how far the business reaches, who its competitors are, and which communities it serves. The other words don’t fit: products is a noun and can’t complete the idea of learning; commit means to dedicate or pledge effort, not to understand; define means to describe or set boundaries, which is related but describes a different action than the process of understanding itself in this sentence.
