Dividend income year

Sec 8 of IT Act creates confusion because of use of 'previous year'. Can you kindly tell which of these dividend incomes will be taxable in the current assessment year (AY 2023-24) for which we are submitting ITR right now:

a- div for fy 21-22: received between 1/4/2022 and 31/3/2023
b- div for fy 22-23 received between 1/4/2022 and 31/3/2023 (=interim div for 22-23)
c- div for fy 22-23 received after 1/4/2023

Thanks in advance and regards!
