Correct Answer:
D. Essential
The synonym of INTRINSIC is Essential.
- Intrinsic means belonging naturally; essential or inherent. For example, the intrinsic value of something is its true, inherent worth.
- Intricate means very complicated or detailed.
- Complicated means difficult to understand or deal with.
- Secret means not known or seen by others.
While intricate and complicated relate to complexity, they do not capture the core meaning of being inherent or fundamental, which "essential" accurately conveys.
