Correct option is B
The correct replacement is option (b).
Explanation:
- The sentence needs noun forms after “Security is ...”. Hence, freedom (noun) is correct, not freed/freeing.
- The word resiliencing is incorrect because it is not used as a standard noun/verb form in formal English. The correct noun is resilience.
- The phrase potential harm is the correct collocation; potent harm is not appropriate here.
Correct segment:
- freedom from, or resilience against, potential harm
Why other options are incorrect:
- (a): Uses resiliencing (incorrect form) and potent harm (wrong collocation).
- (c): freeing from breaks the noun-parallel structure after “Security is”.
- (d): Not correct because the bracketed segment contains errors.
So the correct answer is (b)
