Answer: D

Explanation:

The correct syntax for using the Vb.Net If operator is If(condition1, valueIfTrue, valueIfFalse). The If operator is a ternary operator that returns one of two values, depending on whether the condition is true or false. The condition must be a Boolean expression or a data type that can be implicitly converted to Boolean. The valueIfTrue and valueIfFalse arguments can be any data type, but they must be the same or implicitly convertible to a common type. The If operator uses short-circuit evaluation, which means that it only evaluates the argument that corresponds to the result of the condition.

For example, the following expression returns “Positive” if the variable number is greater than or equal to zero, and “Negative” otherwise:

VB Dim result As String = If(number >= 0, “Positive”, “Negative”)
