The supervisor asked the team to () the customer if there are any delays.

• A. Notify
• B. Inform
• C. Warn
• D. Contact

Answer: (A)

The main idea here is choosing a verb that means giving official information about a delay to a customer. In business English, you typically notify customers when a delay occurs because it signals a formal, timely update that they should expect as part of standard communication about commitments. The word implies an official notice about the situation and its impact. Inform would also work in everyday language, but notify fits the procedural, professional tone often used in supervisor instructions. Warn would carry a sense of caution about danger or risk, which isn’t the intended meaning here, and contact merely means getting in touch without specifying the content of the communication. So, the best choice is to notify the customer if there are any delays.
