I would say option "C. -Oid" would be your answer

The rest of the choices are incorrect.. Because⬇

A. -Cy means 'donating the rank in the office' , think of the word of lunacy as a example for this suffix
B. -Osis means 'donating the actions of something'... just think of the word hypnosis as a example for this suffix
D. -ity means the expression of the state of a particular condition.. just think of the word "jollity" of the example for this suffix
