Selenium Java - JavaScriptExecutor

What will happen if you run this code snippet?

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

AThe button with id 'submitBtn' will be clicked via JavaScript

BA syntax error will occur due to wrong casting

CNo action will happen because executeScript does not click elements

DA runtime exception will occur because btn is not visible

Step-by-Step Solution

Solution:

Step 1: Analyze code correctness
The casting to JavascriptExecutor is correct, the element is found by id, and executeScript calls click on the element.
Step 2: Understand JavaScript click effect
JavaScript click triggers the click event on the element regardless of visibility or overlay issues.
Final Answer:
The button with id 'submitBtn' will be clicked via JavaScript -> Option A
Quick Check:
JS click executes successfully = A [OK]

Quick Trick: JS click triggers click event even if element is hidden [OK]

Common Mistakes:

MISTAKES

Assuming executeScript cannot click elements
