Answer:
The scheme of rhymes in a poetry is always marked by lowercase letters
Step-by-step explanation:
The rhyme scheme is defined and categorized by the lowercase letters (a, b, c, d, etc.). The first set of rhymes are marked as "a". The second as "b", and so on.
Thus, in a poem with the "abab" scheme, the first line rhymes with the third, and the second line rhymes with the fourth. In a poem with a rhyme scheme "abcb", the second line rhymes with the fourth. However, there are no rhymes between the first and third line.
