To achieve this goal, you decide take your secret and cut it into three equal non-overlapping parts to give to each of the there people. Which of the following would be the downsides of this scheme?
A) If one of the three goes rogue or loses the secret, you lose ability to access to your assets.
B) An attacker can steal any one secret and get access to your assets.
C) An attacker gains information about your private key material from stealing any one secret, reducing brute force attack space.
