The correct answer is A. The part of speech
Explanation:
In most dictionaries, the first element in the dictionary entry of a word are abbreviations such as adj. (adjective), v. (verb), n. (noun), etc. that indicate how the word functions, which is known as part of speech. For example, if the word is an adjective this indicates in a sentence the word would modify a noun but does not indicate an action nor modify a verb as these are the functions of other parts of speech. According to this, the abbreviations after a word in a dictionary indicate the part of the speech.
