The correct answer for the average rate of domestic savings (gross) for the Indian economy is currently estimated to be in the range of 20 to 25 percent as depicted in Option 2.

Option 1 suggests a range of 15 to 20 percent. This is lower than the accurate estimated rate.

Option 3 indicates a range of 25 to 30 percent and option 4 suggests an even higher range of 30 to 35 percent. Both these options overestimate the rate of domestic savings in the Indian economy.

Therefore, the correctly estimated range is provided in option 2, i.e., 20 to 25 percent, which correctly reflects the current rate of domestic savings in the Indian economy.
