Directions: Read the following passage carefully and answer the questions given below it. Certain words/phrases are given in bold to help you to locate them while answering some of the questions   In terms of the total energy consumed by different sectors, the largest consumer is understandably the industrial sector, which accounts for nearly half the total energy used in the country today. This is followed by the transport sector which consumes about 25%, the household sector about 14% and the agricultural sector about 9%. The last sector has shown considerable increase in energy use over the last four decades. Among the primary fuels, the relative proportion of coal has decreased from the earlier 80% to 40% and that of oil has gone up from 17% to 44% over the same period.   Total energy consumption in India today is equivalent to 291 million tons of oil of which 26% comes from wood. On a per capita basis it works out to about 1 litre of oil per day, which is extremely low by international standars. The future energy demand depends upon the level of development and also on the people to be affected by it. The energy disparity between the urban and the rural population is at present as wide as between nations on a world wide scale. There is apparently a great need to provide energy in the rural areas and to improve the national figures for energy consumption, limiting its use to those who are already getting the share in bulk.   With the projected rate of population growth, improving upon the per capita energy consumption is Herculean task as our coal reserves and the capacity to import oil cannot be increased beyond a point. There is clearly no escape from the utilization of renewable energy source in a big way if the gap between the desired levels of energy supply and available resources has to be kept at the minimum.

The author is laying great emphasis on which of the following?

(I) Efficient use of energy.

(II) Increasing national indices for energy consumption.

(III) Controlling population growth.

 

A) only I                 

B) only II

C) only III                                 

D)  all the three
