Identify the part (A–E) that contains a grammatical error in the sentence below. If there is no error, choose option E (No error). Sentence (split into parts): A) A high level meeting B) of officials is reporting C) to have discussed D) the issue in great detail.

Introduction:
This sentence tests the correct use of passive reporting structures common in news English: "is reported to have + past participle".

Given Data / Assumptions:

• Subject NP: "A high level meeting of officials".
• Target form intended: passive report.
• Complement: "to have discussed the issue in great detail".

Concept / Approach:
In journalistic style, we say "X is reported to have done Y" to avoid assigning a specific reporter. Using "is reporting" incorrectly makes the subject ("meeting") the active reporter, which is illogical. The correct passive is "is reported". Hyphenation of "high-level" is a stylistic improvement but not the tested error.

Step-by-Step Solution:
1) Recognize reporting construction.2) Choose passive: "is reported", not "is reporting".3) Keep perfect infinitive "to have discussed" to indicate the action happened earlier.4) Full correction: "A high-level meeting of officials is reported to have discussed the issue in great detail."

Verification / Alternative check:
Alternative active: "Reporters say that a high-level meeting of officials discussed the issue in great detail." Meaning matches.

Why Other Options Are Wrong:
A: Noun phrase acceptable; hyphen is optional in many tests.C: "to have discussed" correctly marks prior action.D: Idiomatic prepositional phrase.

Common Pitfalls:
Confusing "is reporting" (progressive active) with "is reported" (passive).

Final Answer:
B (Replace with "is reported")
