Explanation:

- The unemployment rate based on the Usual Principal Status (UPS) provides an estimate of those unemployed for a major part of the year.

- For India during the years 2015-16, the UPS unemployment data is collected through national sample surveys.

- Option 1: 8.7 percent — This figure is generally higher than the typical rates reported for these years in India.

- Option 2: 7.8 percent — Like option 1, this is above the usual rate noted in surveys.

- Option 3: 5.0 percent — This was the unemployment rate noted for 2015-16 under the UPS approach.

- Option 4: 4.2 percent — Lower than the actual rate noted in official surveys for these years.
