All of the following attacks are considered technical attacks except:
A.

B.
Linear cryptanalysis
C.
Rubber hose cryptanalysis
D.

Explanation:
Differential, linear, and algebraic cryptanalysis are attacks towards
symmetric block ciphers. A rubber hose cryptanalysis is a non-technical attack
consisting of assault and battery, when someone is physically threatened and
possibly tortured so that they will hand over a key.
