Unable to trigger the click action on a select option using arguments[0].click() in Selenium

I'm currently utilizing Selenium for automating web applications. I've encountered an issue where I am utilizing .ExecuteScript() to carry out actions such as clicking on a link, with the following syntax:

((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].click()", driver.FindElement(By.XPath("//a[contains(text(),'Login to the Demo')]")));


[Note: I use this approach for every clickable element, as the element may be hidden or not visible on the webpage.] However, this method does not work when dealing with 

<select> <option>item<option> .. </select>


I attempted to click on one of the select options using the code below:

((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].click()", driver.FindElement(By.XPath("//select[@id='form_switcher']/option[5]")));

No action is being taken and no error/exception is thrown.

--Edit start--
However, when I try without using ExecuteScript(), it works perfectly fine:

driver.FindElement(By.XPath("//select[@id='form_switcher']/option[5]")).Click();

--Edit end--

[Note: I am using click to select options in order to trigger the change event.]

If anyone could provide guidance on how to click on a select option using 

((IJavaScriptExecutor)driver).ExecuteScript
, it would be greatly appreciated.

Thank you in advance.

To interact with dropdown menus, it is important to select the option rather than just clicking on it. You can achieve this by identifying the element and setting its index value using code such as element.SelectedIndex = 5;

If you prefer to access the element through JavaScript instead of Selenium, you can use the document.evaluate method available at https://developer.mozilla.org/en-US/docs/Web/API/document.evaluate?redirectlocale=en-US&redirectslug=DOM%2Fdocument.evaluate

This approach involves retrieving the select element using document.evaluate and then specifying the desired index value for SelectedIndex.

It is recommended to follow these steps...

((IJavaScriptExecutor)driver).ExecuteScript("var element = document.evaluate(\"//select[@id='form_switcher']\", document.documentElement, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null); element.SelectedIndex = 5;  return element.fireEvent('event specifics go here')");
