Help to understand which Financial statements to use

Good day,
I am planning to do topic 5 for period 43 and I found two companies with different reporting periods. The main company has year end December 31 and the comparator January 31. I want to know what financial statements I would use seeing that the RAP would be submitted in November? Do I use the three previous full year statements from 2018,2019 and 2020 or I should use quarterly reports to include 2021 results?

I know this is a frequently asked question however I have been looking through the forums as well as the OBU information pack but I am still unsure as to the explicit requirement and I would like to do some ground work as I am awaiting my final ACCA level 2 paper result in July to determine my eligibility.
