Answer:
The answer is indeed letter C) aba aba
Step-by-step explanation:
To determine the rhyme scheme in a poem, we must look at the last word of each line. The last word of the first line is becomes the rhyme "a". When other last words sound similar to it, they are also "a". When they sound different, we give them other letters following the alphabet - b, c, d etc. - every time a new rhyme appears.
Let's analyze the excerpt given:
Do not go gentle into that good night, --> first last word, a
Old age should burn and rave at close of day; --> sounds different than night, b
Rage, rage against the dying of the light. --> rhymes with night, a
Though wise men at their end know dark is right, ---> a
Because their words had forked no lightning they --> rhymes with "they", b
Do not go gentle into that good night. --> a
Thus, the rhyme scheme in this excerpt is aba aba.
