According to Oracle documentation3, when you need to set up a calendar for the year Apr-XX to Mar-YY where YY is the following year, and you would like the periods to be named according to the year they fall in, you should choose Fiscal Year as the format. A Fiscal Year format enables you to define periods based on fiscal years that span two calendar years. Therefore, option A is correct. Option B is incorrect because a Calendar Year format defines periods based on calendar years that start on January 1st and end on December 31st. Option C is incorrect because a Period format defines periods based on any number of days or weeks. Option D is incorrect because a Year format defines periods based on calendar years that start on any month other than January and end on any month other than December.
