To solve the analogy "Grueling is to challenging as unnecessary is to _____", we need to find a word that has a similar relationship to "unnecessary" as "challenging" has to "grueling."

1. Analyze the relationship:

   • Grueling and challenging both describe something that requires a lot of effort or is difficult, with "grueling" being a more extreme form than "challenging."
   • We need to find a word that relates to "unnecessary" in a similar way.

2. Consider the options:

   • Languorous: Suggests a state of weakness or fatigue; not a synonym for unnecessary.
   • Delectable: Pertains to something delicious; not related to unnecessary.
   • Nonplussed: Means to be perplexed or confused; does not relate to unnecessary.
   • Extraneous: Means not essential or irrelevant; closely aligns with unnecessary.

3. Determine the best fit:

   • Extraneous fits well as it implies something that is unnecessary or not needed, similarly to how grueling is an extreme form of challenging.

Final Answer

The correct completion is extraneous.
