A. Syntax error
B. Accessing a variable or function that is not defined
C. Division by zero
D. None of these

Solution

C. Division by zero

Explanation

Division by zero is not an error in JavaScript: it simply returns infinity or negative infinity. There is one exception, however: zero divided by zero does not have a well-defined value, and the result of this operation is the special not-a-number value, printed as NaN.
