Spot the error; choose ‘‘No error’’ if none. Sentence: He has in his possession a price collection of very old coins and some ancient paintings.

Introduction / Context:
This question tests vocabulary accuracy and collocation. The intended phrase in formal English is ‘‘a prized collection’’ (highly valued), not ‘‘price collection.’’ The latter is unidiomatic and changes the meaning.

Given Data / Assumptions:

• Noun phrase following the article ‘‘a’’: ‘‘price collection of very old coins.’’
• Parallel addition: ‘‘and some ancient paintings’’ → fine.
• Possession phrase ‘‘has in his possession’’ → formal but acceptable.

Concept / Approach:
‘‘Prized’’ is an adjective meaning ‘‘valued highly; treasured.’’ ‘‘Price’’ is a noun; as an adjective it would suggest ‘‘price list’’ or ‘‘price index,’’ not the value judgment intended here. Thus the correct collocation is ‘‘a prized collection of very old coins.’’ Some also use ‘‘precious’’ or ‘‘valuable.’’

Step-by-Step Solution:
Identify wrong word: ‘‘price’’Replace with correct adjective: ‘‘prized’’ (or ‘‘valuable’’).Corrected segment: ‘‘a prized collection of very old coins.’’

Verification / Alternative check:
Corpus and dictionary usage confirms ‘‘prized collection’’ is standard; ‘‘price collection’’ returns as an error or means a data set of prices, which is not the context here.

Why Other Options Are Wrong:
A and B are acceptable formal phrasing. D correctly continues the coordinated object. The lexical error is solely in C.

Common Pitfalls:
Confusing ‘‘prize’’ (noun) with ‘‘prized’’ (adjective), and accidentally substituting ‘‘price.’’ Also, avoid placing a full stop before ‘‘and’’ that would create a fragment; this version already fixes that.

Final Answer:
price collection of very old coins.
