Correct Answer: D
Explanation:
The words, ‘dearth’ and ‘inadequacy’ mean the same and the words, ‘profusion’ and ‘abundance’ carry the same meaning. The missing word is being used in the context of ‘being bred’. On comparing these four words, it can be seen that D and E are the correct answers as ‘profusion’ and ‘abundance’ fit in better with the context in which the missing word has been used.
