Introduction / Context:
This problem checks subject–verb structure inside a relative clause and capitalization. You must identify the erroneous fragment.
Given Data / Assumptions:
- The main subject is “The environment … is undergoing …”.
- Within the relative phrase “in which …,” a full clause is expected.
- “Frenetic” is a common adjective and should not be capitalized mid-sentence.
Concept / Approach:
Inside “in which …,” the phrase “companies operating” is non-finite and needs a finite verb or an auxiliary to complete the clause if it is intended as a clause. The most natural fix is “companies operate” (simple present) or “companies are operating” (present progressive).
Step-by-Step Solution:
Part A: “The environment in which” — correct start to a relative prepositional phrase.Part B: “companies operating” — incorrect; either “companies operate” or “companies are operating” is required for a complete clause.Part C: “today is” — subject–verb agreement with “environment” is correct.Part D: “undergoing Frenetic changes.” — grammatical but “Frenetic” should be lowercase; however, the primary grammatical error lies in Part B.
Verification / Alternative check:
Corrected sentence: “The environment in which companies operate today is undergoing frenetic changes.” Reads smoothly.
Why Other Options Are Wrong:
A and C are correct; D’s capitalization is stylistic, but the grammatical fault is in B, which is the targeted error.
Common Pitfalls:
Overlooking the need for a finite verb inside relative constructions.
Final Answer:
companies operating
