Internal rhyme implies two or more words in a line have similar sounds; this includes vowel or consonant sounds. From the options, options 1, 2, and 4 are examples of internal rhyme. For example, in the first option "seed" and "feed" have the same ending sound. This does not occur in the option "and traded them to Lou" because in this short line there are not repeating sounds, and therefore this not an example of internal rhyme.
