In JavaScript, to create a conditional statement, you typically use structures that evaluate conditions and execute blocks of code based on those evaluations. An if statement is the most common way to implement this. It checks a specified condition and executes a block of code if the condition evaluates to true. Additionally, a switch statement provides a way to execute different blocks of code based on the value of a variable or an expression. This allows for more organized multiple condition checks compared to chaining several if statements.

Both the if and switch statements serve the purpose of determining which code block to execute based on varying conditions, making them essential tools for branching logic in programming. This flexibility is what makes option B the correct choice for representing how conditional statements are created in JavaScript.
