Step-by-step explanation:
The question asks which of the listed options is an enemy of clear writing. The correct answer is b) Trite expressions. Trite expressions are overused phrases or clichés that can make writing feel stale and unoriginal.
Using these expressions can undermine the freshness and clarity of writing. On the other hand, utilizing an active voice typically makes sentences clearer and more direct because they indicate the subject performing the action. Directness in writing means being straightforward and to the point, which enhances clarity and comprehension.
Strategies that encourage clarity and grace in writing should be prioritized over those that can cause writing to become ambiguous or dull.
