Step 1: India's fish production rose steadily through the early 2020s due to aquaculture growth.
Step 2: 142.56 lakh tonnes fits an earlier year and 172.60 lakh tonnes fits a later year in this trend, so both are ruled out for 2020-21.
Step 3: The official figure for 2020-21 is approximately 162.48 lakh tonnes, confirming option (3) is correct.
