Step 1: The time is 9:15 a.m., which is before noon.
Step 2: For a.m. times, the 24-hour hour is the same as the 12-hour hour. 9 a.m. stays as 09.
Step 3: Write the hour with two digits: 09. Write the minutes: 15.
Step 4: Combine: 0915.
Answer: 9:15 a.m. = 0915 in 24-hour time.
Correct answer: 0915
