You have a dictionary dict with string keys and int values. How can you create a new dictionary containing only entries with values greater than 10?

AUse dict.Filter(kv => kv.Value > 10);

BUse LINQ: dict.Where(kv => kv.Value > 10).ToDictionary(kv => kv.Key, kv => kv.Value);

CUse dict.Select(kv => kv.Value > 10);

DUse dict.RemoveWhere(kv => kv.Value <= 10);

Step-by-Step Solution

Solution:

Step 1: Identify correct LINQ method for filtering
Where filters entries by condition, ToDictionary converts result back to dictionary.
Step 2: Analyze each option
Use LINQ: dict.Where(kv => kv.Value > 10).ToDictionary(kv => kv.Key, kv => kv.Value); correctly filters and creates new dictionary; others use invalid or non-existent methods.
Final Answer:
Use LINQ: dict.Where(kv => kv.Value > 10).ToDictionary(kv => kv.Key, kv => kv.Value); -> Option B
Quick Check:
Filter dictionary with Where + ToDictionary [OK]

Quick Trick: Use LINQ Where and ToDictionary to filter dictionaries [OK]

Using non-existent Filter or RemoveWhere methods
