English grammar — Spot the error (choose the segment that contains a grammatical error; choose ‘‘No error.’’ if the sentence is correct). Sentence: You should inform your superiors about all those events which are directly related to your work.

Introduction / Context:
The task is to spot any grammatical or usage error in a complete sentence. Focus areas include verb patterns, preposition choice, relative clauses, and adverb placement.

Given Data / Assumptions:

• The verb is “inform,” which typically takes a direct object plus a prepositional phrase: “inform someone about something.”
• A defining relative clause “which are directly related to your work” modifies “events.”
• Adverb “directly” modifies the participial adjective “related.”

Concept / Approach:
Check each chunk for standard collocations and clause structure. “Inform + person + about + thing” is correct. “Which are” for a defining clause is acceptable in formal English; “that are” would also be fine.

Step-by-Step Solution:

Verification / Alternative check:
Alternative phrasing (“that are directly related…”) is equally correct; choosing “which” does not introduce an error here.

Why Other Options Are Wrong:

• No segment A–D contains a grammatical mistake or faulty collocation.

Common Pitfalls:
Believing “which” cannot be used in restrictive clauses. In formal British and international English, “which” is acceptable; American style often prefers “that,” but “which” is not wrong.

Final Answer:
No error.
