Identify a synonym for "advantageous."

The term "advantageous" implies something that provides a benefit or is favorable in a particular situation. In this context, "beneficial" serves as a direct synonym because it conveys the idea of producing positive effects or being helpful. Both words suggest a sense of gain or improvement, making "beneficial" the correct choice.

On the other hand, the other options convey contrasting meanings. "Harmful" indicates something that causes damage or injury, "neutral" suggests a lack of significant impact, and "detrimental" refers to something that causes harm or disadvantage. These terms do not align with the positive connotation of being advantageous.
