In the data mapping, which letter corresponds to 'month'

• A. y
• B. n
• C. m
• D. t

Answer: (C)

Time unit mappings use single-letter codes that map clearly to the unit. Month is best represented by the letter that starts the word month, because it makes the code intuitive and unambiguous. Other letters don’t correspond to a standard month abbreviation, so they would be confusing. Therefore, month maps to m.
