Final answer:
The word 'surreptitious' is not derived from 'plicare' or 'prehendere'; it comes from Latin 'surrepticius', meaning 'snatched secretly', making it the correct answer.
Step-by-step explanation:
The word that is not derived from plicare or prehendere is surreptitious. Here's why:
- Imply is derived from plicare, meaning to fold.
- Impregnable comes from prehendere, meaning to seize or grasp.
- Surreptitious does not come from either root; it is derived from Latin surrepticius, which means 'snatched secretly'.
- Reprisal is also from prehendere.
- Entrepreneur comes from the French verb entreprendre, meaning to undertake, and does not derive from either Latin root mentioned.
However, as surreptitious is not related to the Latin roots plicare or prehendere, answer choice C is the correct answer.
