Question

Consider the following statements regarding the Indian ocean conference.
i. The Indian Ocean conference has been initiated by the Indian Ocean Rim Association.
ii. It is an annual conference that aims to bring together Heads of states/ Governments, Ministers, thought leaders, scholars, diplomats, bureaucrats and practitioners from across the region on a single platform.
iii. Fishing in the Indian Ocean now accounts for almost of the world total.
Which of the above statements is/are correct?
A) i, ii
B) ii only
C) i, iii
D) ii, iii

Answer 1

Hint: The water present in rivers and ponds are likely to be polluted more than the water we drink. Hence it is obvious that water in ponds have more Biochemical oxygen demand and less amount of BOD is present in potable water. Wastewater management is a treatment to purify water bodies in an efficient manner. The pollution water is facing and it is affecting the aquatic animals in a very harsh way.

Complete answer:
Option A i, ii: - Indian Ocean conference has been initiated by the Indian Ocean in male, Maldives and It is a conference for discussing water issues.
Option A is not the correct answer.
Option B ii only: only- it is an annual conference that aims to bring Heads of states/ Governments, Ministers, thought leaders, scholars, diplomats, bureaucrats and practitioners from across the region on a single platform.
Option B is the correct answer.
Option C i, iii: - conference is being held in for targeting the water issues all over the world and fishing in the Indian ocean counts for of the world.
Option C is not the correct answer.
Option D ii, iii: - Water bodies have plants which help to purify. And due to the outflow of chemicals in the body’s plants are dying too, they cannot withstand the harsh chemicals. So are the marine animals and fishes.
Option D is not the correct answer.

Hence the correct answer is option B.

Note:
Diseases spread by unsafe water include cholera, giardia, typhoid, dysentery, Amoebiasis. BOD is biochemical oxygen demand also known as biological oxygen demand, which is required by the aquatic plants and organisms to breakdown the complex inorganic substituents into organic simpler units. To solve the water problems integrated waste water treatment is being used.
