Country A is said to dominate B or A > B if A has higher percentage in total coverage for both drinking water and sanitation facilities, and, B is said to be dominated by A, or B < A.

A country is said to be on the coverage frontier if no other country dominates it. Similarly, a country is not on the coverage frontier if it is dominated by at least one other country.

 India is not on the coverage frontier because

  1. it is lower than Bangladesh in terms of coverage of drinking water facilities.
  2. it is lower than Sri Lanka in terms of coverage of sanitation facilities.
  3. it is lower than Pakistan in terms of coverage of sanitation facilities.
  4. it is dominated by Indonesia.
    1. A and B
    2. A and C
    3. D
    4. None of these

Best answer
Country A is said to dominate B or A > B if A has higher percentage in total coverage for both drinking water and sanitation facilities, and, B is said to be dominated by A, or B < A.

So from the table we can see that :-

india>China,Nepal

Philippines>India,Indonesia,Srilanka,Nepal,China,Pakistan

Bangaladesh>India,China,Nepal,Pakistan

A country is said to be on the coverage frontier if no other country dominates it. Similarly, a country is not on the coverage frontier if it is dominated by at least one other country.

So India is not on  the coverage frontier because India is Dominated by Bangaladesh and Philippines
