The best-selling company/brand in a market.

• A. Market leader
• B. Market follower
• C. Market position
• D. Market share

Answer: (A)

The main idea is identifying the brand with the highest sales in a market. That brand is described as the market leader, because it holds the top position in terms of overall sales and influence within the market. Market leader implies not just a high number, but the leading role in performance, visibility, and often distribution strength.

Market share is a numeric measure of how much of the total market sales a brand owns, expressed as a percentage. It tells you how big the slice is, but it’s not the label itself. Market position describes how a brand is perceived and where it sits strategically among competitors, which can be leader, challenger, follower, etc. Market follower refers to brands that lag behind the leader.

So—the best-selling brand is the market leader.
