b. 3892.22
c. 3,892.22
d. $3,892.22

Answer 1

The value of variable 's' after formatting will be "3,892.22". This follows the C# formatting conventions used within interpolation syntax with custom numeric format strings.

Step-by-step explanation:

The question is asking about a formatted string in C# programming, particularly the format specifier used with the variable d to create the variable s.

The 'decimal' keyword is used to declare a variable that can store a fixed-point number and 'string' keyword is used to declare a variable for text. The formatted string uses the composite format string "{d:##,##0.00;(##,##0.00)}", which contains a format string with sections separated by a semicolon. The first section is a positive number format, and the second one (if present) is for negative numbers.

Since the number is positive and the first format section is used, the value of the variable s after the statements are executed would be "3,892.22". This includes a comma as the thousands separator and two decimal places as specified by the format string.
