Statement: The use of non-conventional sources of energy will eliminate the energy crisis in the world.
Conclusion: I. Modern technology is gradually replacing the conventional sources of energy.
II. The excessive exploitation of environment has led to depletion of conventional sources of energy.

Options

A. if conclusion I follows
B. if conclusion II follows
C. if both I and II follow
D. if either I or II follows,

Answer

B

The statement says that the user of non-conventional energy sources will replace (eliminate) the energy crisis. It does not say that the replacement is already on. Hence, the first conclusion is invalid. The second is valid because there is an energy crisis.
