Correct Answer: C
Explanation:
The missing word describes what others did in respect of the explanations of the evidence. ‘Elucidate’ would be an incorrect option for placing in the blank as ‘elucidate’ and ‘explain’ mean the same and it is the evidence which is being explained; the explanations cannot be explained further. Out of the remaining answer options, ‘proffered’ and ‘suggested’ are the only two words that carry the same meaning and hence, C and E are the correct answers.
