PUERILE

The correct answer is Callow.

Step-by-Step Explanation:

1. Understand the target word:
The word PUERILE is an adjective derived from the Latin word puer (meaning "boy" or "child"). It is used to describe behavior or attitudes that are childish, silly, immature, or trivial.

2. Analyze the options:

• Judicious: Having, showing, or done with good judgment or sense; wise and sensible. This is opposite in meaning to puerile.
• Adept: Very skilled or proficient at something. This does not relate to childishness or immaturity.
• Sophisticated: Having, revealing, or proceeding from a great deal of worldly experience and knowledge; refined. This is also an antonym of puerile.
• Callow: Inexperienced, immature, or lacking adult sophistication (often used to describe a young person). This closely mirrors the meaning of "puerile."

3. Conclusion:
Since both puerile and callow refer to immaturity and childishness, Callow is the option closest in meaning to PUERILE.
