March [3][12]

Explanation:

A two-dimensional array named Months stores the months of the year in the first column and the days of each month in the second column. March[3][12]

the months is represented as 1-12 while the days are represented as 1-30 therefore to represent the element that stores March 12 where March is the third month of the year, it will be represented as March [3][12]  which simply means the 12th of March  regardless of the year because there is no third column for that since it is a two-dimensional array
