First of all, you need to know what a suffix is. It is an addition that you basically glue onto a word - you have the basic form of a word (for example, play), and then you add the suffix at the end (-ing), and you get a new word (playing).
Having this in mind, there are two correct options here: hysterical (derived from hysteric + suffix -al), and contemptible (derived from contempt + suffix -ible).
