(III) environmental sustainability, and external imbalance

Options

A. Only III

C. Both I and III
D. Only II

Answer

B

Explanation

The error in I is that the preposition 'on' must be present after the verb 'brought'. The phrase 'brought on' means 'led to the development of.' The correct perposition to be used after the word 'challenges' is 'to' and not 'of'. The point mentioned is something positive so 'to' is the correct preposition. Had it been a problem mentioned here the preposition 'of' would have been correct.
