Glossary means most nearly

• A. Lewd
• B. Dictionary of selected terms in a particular book or field
• C. Fictitious name
• D. Entire range

Answer: (B)

A glossary is a focused, mini-dictionary that lists terms used in a specific book or field and gives brief definitions for them. It’s created to help readers understand the specialized language they’ll encounter in that work, often including concise explanations or usage notes for each term. This makes it the best fit for describing a “dictionary of selected terms in a particular book or field,” rather than anything else.

The other ideas don’t align with what a glossary does: it’s not about lewd content, not a fictitious name, and not the entire range of all terms in general language—it's a curated set of terms defined for a particular context.
