Breakdown of the Problem

1. Analyze the word "who" in the context of the sentence.
2. Identify the type of pronoun it represents.

Relevant Concepts

• Personal Pronoun: Refers to specific persons or things (e.g., I, you, he, she, it).
• Relative Pronoun: Introduces a dependent clause and relates to a noun mentioned previously (e.g., who, whom, whose, which, that).
• Demonstrative Pronoun: Points to specific things (e.g., this, that, these, those).
• Interrogative Pronoun: Used to ask questions (e.g., who, what, which).

Analysis and Detail

The word "who" is commonly used to inquire about identity or to introduce a clause. In this case, "who" refers to the people responsible for training frontliners, making it an interrogative pronoun because it is used to ask about the identity of that group. However, since "who" is appearing in a way that it could relate to a clause, it could also be seen as a relative pronoun.

Verify and Summarize

While "who" can function in both interrogative contexts (asking a question) and relative contexts (relating to a noun), based on the provided options and the nature of the sentence structure, the most suitable choice to classifying the word "who" in this context is: Relative pronoun.

Final Answer

The correct answer is Relative pronoun.
