Show answer & explanation
Correct answer: C
Explanation
Correct Answer: proficient in managing complex databases, yet she
Explanation
• The linking verb is requires a predicate adjective (proficient) rather than an adverb (proficiently) to describe the subject pronoun 'She'.
• The adjective proficient is conventionally followed by the preposition in (or at) + gerund (managing).
• Therefore, proficient in managing is grammatically sound.
Quick Tip: Use adjectives after linking verbs (is, am, are, was, were) when modifying the subject: She is skilled/proficient (not skillfully/proficiently).
