Answer is Right!
The correct answer is C. in.
The preposition “in” is used to express belief or confidence in something. For example, “I believe in ghosts.”
The preposition “of” is used to express possession or ownership. For example, “I am afraid of ghosts.”
The preposition “on” is used to express a location or position. For example, “Ghosts are said to live on the other side.”
The preposition “for” is used to express a purpose or reason. For example, “I am looking for ghosts.”
In the sentence “Do you believe in ghosts?”, the preposition “in” is used to express belief or confidence in ghosts.
