In PHP, variable names should start with a letter or underscore. They cannot start with a number. Therefore, the variable name $4bears is not valid.

The correct way to write the code would be to use a valid variable name, such as:

$_4bears = $bears-&gt;getFirst4();

So, the correct answer is B) No.
