Final answer:
In the context of a semantic domain, 'unmarked' refers to a word or concept that is considered typical or central within that domain. The correct answer is 'Central'.
Step-by-step explanation:
In the context of a semantic domain, 'unmarked' refers to a word or concept that is considered typical or central within that domain.
It represents the standard or most common meaning associated with that domain.
In contrast, 'marked' words or concepts deviate from the norm and are considered atypical or peripheral within the semantic domain.
For example, in the semantic domain of fruits, 'apple' would be an unmarked word because it is a typical and common fruit.
On the other hand, 'dragon fruit' would be a marked word because it is less common and less typical within the domain of fruits.
Therefore, the correct answer is A) Central.
