Correct Answer
A. $(selector).action()

Explanation
The correct answer is $(selector).action(). In jQuery, the basic syntax starts with the dollar sign ($), followed by parentheses that contain a selector, and then a period (.) followed by an action. This syntax allows you to select elements from the DOM using the selector and perform actions on them using the specified action.

Which of the following selects an HTML element with id test?
- A.
  
  $(".test")
- B.
  
  $("#test")
- C.
  
  $(test)
- D.
  
  $("test")
Correct Answer
A. $(".test")

Explanation
The correct answer is $(".test"). This is because the "$" symbol in JavaScript is used to select elements in the DOM (Document Object Model). The syntax $(".test") uses the class selector "$" followed by parentheses and the class name "test" inside quotation marks. This will select all HTML elements with the class name "test". On the other hand, $("#test") would select an element with the id "test", $(test) would select a variable named "test", and $("test") would select all HTML elements with the tag name "test".
