Which of the following is the correct syntax to sort a list of integers named numbers in ascending order using OrderBy?

Anumbers.OrderBy();

Bnumbers.OrderBy(n);

Cnumbers.OrderBy(n => n);

Dnumbers.OrderBy(n => );

Step-by-Step Solution

Solution:

Step 1: Check the correct lambda syntax
OrderBy requires a key selector function like n => n to specify sorting key.
Step 2: Validate each option
numbers.OrderBy(n => n); uses correct lambda syntax. numbers.OrderBy(); misses the key selector. numbers.OrderBy(n); passes a variable, not a lambda. numbers.OrderBy(n => ); has incomplete lambda syntax.
Final Answer:
numbers.OrderBy(n => n); -> Option C
Quick Check:
OrderBy needs a key selector lambda [OK]

Quick Trick: OrderBy always needs a key selector lambda like n => n [OK]
