That part of a brand which can be recognized but is non-utterable is called:

Brand Mark

The correct answer is Option (1) → Brand Mark

A brand mark is a non-verbal symbol, design, or visual image that uniquely identifies a product or company. It's a visual cue that consumers can instantly recognize without needing to read or hear a name.

Here's why the other options are incorrect:

• Brand Name: This is the verbal, utterable part of a brand, such as "Nike" or "Apple."

• Trade Mark: This is the legal protection given to a brand's elements, including both the brand name and the brand mark, to prevent unauthorized use.

• Patent: This is a legal right that protects an invention or a new process, not the brand's identity.
