Concept:A trade mark is a distinctive sign used to identify and distinguish a company’s products from others.
Explanation:The question asks for a symbol, title, or design that identifies the company and its products.
A trade mark includes logos, symbols, designs, and even certain words or titles registered legally to protect the product’s identity.
A brand name is only the name given to a product, not the whole symbol or design.
A trade name is the official name under which a company operates, while a patent right protects an invention or process.
Therefore, the most accurate choice is a trade mark.
Answer:Option B — trade mark.
