The correct answer reflects the angles at which Medeco angular bitted keys are cut, which is specifically designed for enhanced security and functionality in locking mechanisms. Medeco keys are known for their unique angular cuts that are intended to provide resistance against unauthorized duplication and manipulation.

In the correct answer, the right and left cuts at 20 degrees offer a specific angle that aids in the precise alignment of the key within the lock mechanism. The center cut is set at 90 degrees, which ensures that the key engages fully with the lock when inserted. This combination of angles contributes to the overall security features of Medeco locks, as the geometry of the key works in conjunction with the pin and tumbler system to prevent picking and key duplication.

This precise angular cutting is crucial for the correct functioning of security systems, and understanding these specifications can help locksmiths appreciate the engineering behind high-security locks.
