To determine the error in the given code, we can analyze the options presented:

1. A: Double-quote strings can't span multiple lines.
2. B: There is no error.

Breakdown of the Code

• The code provided is:

  var str = "Hello\nWorld";
  

• This code defines a string variable str that contains a newline character (\n), which separates "Hello" and "World".

Relevant Concepts

• In JavaScript, strings can include newline characters through escape sequences like \n.
• Double-quoted strings in JavaScript can indeed span multiple lines if you use escape sequences properly.

Analysis and Detail

1. The \n character is interpreted as a newline. Therefore, the string str will store:

   Hello
   World
   

2. The syntax is correct, and the intention of spanning lines using the newline escape character is valid.

Verify and Summarize

• There's no syntax error in the code. The string "Hello\nWorld" is perfectly valid in JavaScript.

Final Answer

B: There is no error.
