Selenium Java - JavaScriptExecutor

What is wrong with this code?

JavascriptExecutor js = (JavascriptExecutor) driver;
WebElement element = driver.findElement(By.id("btn"));
js.executeScript("arguments[0].click();");

AThe casting to JavascriptExecutor is incorrect

BThe JavaScript code syntax is wrong

CThe locator By.id("btn") is invalid

DThe element argument is missing in executeScript call

Step-by-Step Solution

Solution:

Step 1: Check executeScript parameters
The script uses arguments[0].click() but does not pass the element as an argument, so arguments[0] is undefined.
Step 2: Verify other parts
Casting and locator are correct; JavaScript syntax is valid if argument is passed.
Final Answer:
The element argument is missing in executeScript call -> Option D
Quick Check:
Missing argument in executeScript = B [OK]

Quick Trick: Always pass element as argument when using arguments[0] in JS [OK]

Common Mistakes:

Not passing element argument
Misunderstanding executeScript parameters
Assuming locator or casting is wrong
