I am writing to i______ about a new training course in October.

• A. Inform
• B. Inquire
• C. Imply
• D. Inspire

Answer: (B)

Choosing the right verb to request information in a formal email is about using a word that accurately matches the action you want to take. In this sentence, the best choice is inquire, because it is a formal way to ask for details and it naturally pairs with a topic introduced by about. Saying I am writing to inquire about a new training course in October communicates that you’re seeking information and specifics about that course.

Inform would require a direct object to complete the thought, such as informing you, and without that object the sentence feels incomplete. Imply means to suggest something indirectly, which isn’t what you’re doing here. Inspire means to motivate or encourage, which doesn’t fit the purpose of requesting information. Using inquire about keeps the tone professional and precise, making the intention of the email clear.
