Which sculpture at the CIA building contains four encrypted messages, of which three have been decoded?

• A. Kryptos
• B. Toynbee Tiles
• C. Wow! Signal
• D. Cicada 3301

Answer: (A)

Kryptos is a sculpture by artist Jim Sanborn at the CIA headquarters. It hides four separate encrypted passages, and over the years three of those passages have been deciphered while the fourth remains unsolved. This combination—a sculpture at the CIA with four encrypted messages, three decoded and one still a puzzle—fits the description in the question perfectly. The other options aren’t sculptures at the CIA building and don’t present a four-part cipher, so they don’t match this scenario.
