What is the best definition of 'conversely'?

• A. Reciprocally
• B. In a contrary manner
• C. In the same way
• D. On the other hand

Answer: (A)

Concurrently showing an opposite or reverse relationship between two ideas is what conversely is aiming for. It signals that what follows presents the flip side of what came before, often describing changes that move in inverse directions with respect to each other. That nuance makes reciprocally the best fit here, because it directly highlights how two factors relate in a mutual opposite way. The option about doing things in a contrary manner is close in meaning but less precise for describing this paired, opposite relationship; in the same way would be wrong because it signals similarity rather than contrast; on the other hand is a general contrast marker in discourse but doesn’t emphasize the reciprocal change between two related ideas.
