1. C
Prefixes come at the beginning of words.
2. B
Un- at the beginning of words can be a prefix.
3. A
Un- means not.
4. B
Re- at the beginning of words can mean again. Another meaning of re- is backwards e.g. in repel which means push back.
5. B
The suffix -less means without; hence, fearless means without fear (brave).
6. C
Un- is the prefix, break is the root, and -able is the suffix, so the word unbreakable has both a prefix and a suffix.
