Find the error in this code:

internal class Data {
    private int value;
}
class Program {
    static void Main() {
        Data d = new Data();
        d.value = 10;
    }
}

ANo error, code is correct

BCannot access private field 'value' outside class Data

CMissing public modifier on class Program

DCannot create instance of internal class Data

Step-by-Step Solution

Solution:

Step 1: Check access to private field
The field 'value' is private inside Data, so it cannot be accessed from Program.
Step 2: Confirm instance creation is allowed
Data is internal, accessible within same assembly, so creating instance is allowed.
Final Answer:
Cannot access private field 'value' outside class Data -> Option B
Quick Check:
Private fields inaccessible outside their class [OK]

Quick Trick: Private fields block access even within same assembly [OK]
