Which is the correct format when creating a conditional expression?

The correct format for creating a conditional expression is demonstrated in the option you selected. In programming, particularly in languages that support conditional statements, the use of "if," "else if," and "else" provides a clear, structured way to evaluate different conditions sequentially.

In this format, "if(Length==5)(150)" checks the first condition: if the variable Length is equal to 5, then the expression evaluates to 150. If that condition is not met, the statement moves to the next part, "else if(Length==4)(195)," which checks if Length equals 4 and, if true, the expression evaluates to 195. Lastly, if neither of the previous conditions is satisfied, the final clause, "else(25)," serves as a default case that will provide the value 25.

This logical flow is essential, as it allows for multiple potential outcomes based on the evaluation of the specified conditions, making the conditional expression both clear and efficient in its execution. The structured format used in this answer adheres to standard programming practices, facilitating understanding and readability.

The other options provided may not utilize the recognized syntax for conditional expressions effectively or have structural issues that do not align with conventional programming constructs, leading to ambiguity
