We can't really help you because you didn't give us any of your options to choose from.
However, I can try and explain to you what internal rhyme is, so hopefully you will be able to do this on your own.
An internal rhyme is also known as middle rhyme, and it refers to a type of rhyme which occurs within the same line. You know that the regular rhyme refers to multiple lines rhyming, but when it comes to internal rhyme, words within one single line rhyme.
Here is an example:
My unusual <u>style</u><span><u> </u>will </span><span>confuse you a <u>while.</u></span>
The answer is the first one and the third one
Answer:
particles is a small portion of matter
Number one is an allusion
Number two is a metaphor because it is comparing the dudes face to a white sheet but it didnt use like or as so its not a simile.
Number three therefore would be a simile because it uses the word as to compare two things.
