Explanation:

Let’s break it down:

- The Economic Survey 2021-22 makes it clear: the agriculture and allied sectors weathered Covid-19 better than most other areas.

- The exact growth rate it recorded in 2020-21 was 3.6%.

- Here's what the other options mean:

- 2.9% was agriculture’s growth rate in some earlier years, not during the pandemic.

- 3.1% and 3.9% are close but not the figure cited for 2020-21.

- 4.5% is higher than any recent recorded value for this sector.

- So, option 1 (3.6%) is absolutely correct.
