hard🚀 Application Q8 of 15

C Sharp (C#) - Collections

Avar dict = new Dictionary<string, int> { ("key1", 10), ("key2", 20) };

Bvar dict = new Dictionary<string, int> { {"key1", 10}, {"key2", 20} };

Cvar dict = new Dictionary<string, int> { "key1" = 10, "key2" = 20 };

Dvar dict = new Dictionary<string, int> { "key1": 10, "key2": 20 };

Step-by-Step Solution

Solution:

Step 1: Understand dictionary initialization syntax
Dictionary initialization uses braces with each key-value pair inside braces separated by commas.
Step 2: Evaluate options
var dict = new Dictionary { {"key1", 10}, {"key2", 20} }; uses correct syntax with braces for each pair; others use invalid tuple or indexer syntax.
Final Answer:
var dict = new Dictionary<string, int> { {"key1", 10}, {"key2", 20} }; -> Option B
Quick Check:
Dictionary pairs use braces {key, value} in initialization [OK]

Quick Trick: Use braces {key, value} pairs to initialize dictionaries [OK]
