Correct answer: C
Concept
In a word-swap (sentence-correction) item, exactly the bold words sitting in each other's slot are interchanged so the sentence becomes both grammatically and contextually correct. The method is to first read the sentence and locate the part that already reads naturally (leave those words alone), then isolate the part that breaks down and test which single pair of bold words, when exchanged, restores correct grammar and meaning.
Applying it
The four bold words are: A = "transforms", B = "diagnostics", C = "era", D = "ushering".
Read the opening clause: "Artificial Intelligence transforms healthcare with precise diagnostics and personalized treatments". The verb "transforms" (A) agrees with the subject and "diagnostics" (B) fits "precise ___", so A and B are already in their correct slots.
Read the closing clause as given: "era in a new ushering of medical advancements". This is meaningless: "era in a new ___" has no head noun and "ushering of medical advancements" is not idiomatic.
Swap C and D. "ushering" is a present participle that introduces a result clause, and the fixed idiom is "usher in a new era". So the clause becomes "ushering in a new era of medical advancements", which is correct.
Cross-check
Reassembled sentence: "Artificial Intelligence transforms healthcare with precise diagnostics and personalized treatments, ushering in a new era of medical advancements." It is grammatical and meaningful, and only the C-D pair had to be exchanged. Hence the required interchange is C-D.
