Double.TryParse() method checks if the string value provided in the first parameter can be successfully converted to a double-precision floating-point number, and stores the converted value in the second parameter as an output parameter. If the conversion is successful, the method returns true, and the converted value is stored in the output parameter. Hence, option B will return a Boolean value of true and store it in blnPriceOK only if the txtPrice.Text value can be converted to a double-precision floating-point number.
