Which of the following words is synonymous with the word clandestine?

The word "clandestine" refers to something that is kept secret or done secretively, often because it is illicit or unauthorized. Therefore, a word that aligns with this meaning would be "surreptitious." This term also conveys a sense of stealth or secrecy, describing actions carried out in a way that avoids notice or attention, often to conceal the truth about something.

In contrast, the other words presented do not share this meaning. "Destiny" refers to the events that will necessarily happen to a particular person or thing in the future, which does not relate to secrecy or hidden actions. "Open" indicates something that is not closed or concealed, directly opposing the meaning of clandestine. Similarly, "exposed" suggests that something is revealed or made visible, which again does not align with the idea of something being kept secret or hidden. Thus, "surreptitious" is the only option that matches the essence of "clandestine."
