During the adverse effects of COVID-19 in 2020-21 in India, the sector that witnessed positive growth was option 2, which is electricity, gas, water supply, and other utility services.

Option 1, which is mining and quarrying, may have been negatively impacted due to the lockdown measures and reduced demand for resources during the pandemic.

Option 3, which is financial, real estate, and professional services, may have also experienced a slowdown as businesses and individuals faced economic uncertainty and reduced spending.

Option 4, which is public administration, defense, and other services, may have seen some growth due to increased government spending on healthcare and relief measures but overall growth in this sector may have been limited.

It is important to note that the impact of COVID-19 on different sectors of the economy varied. While some sectors experienced negative growth, others may have seen positive growth or remained relatively unaffected.
