Consider the following array, called $multi_array. How would the value cat be referenced within the $multi_array array?

<?php
$multi_array = array("red",
"green",
42 => "blue",
"yellow" => array("apple",
9 => "pear",
"banana",
"orange" => array("dog",
"cat",
"iguana")
)
);
?>

• $multi_array['yellow']['apple'][0]
• $multi_array['blue'][0]['orange'][1]
• $multi_array[3][3][2]
• $multi_array['yellow']['orange']['cat']
• $multi_array['yellow']['orange'][1]
• I don’t know

$multi_array['yellow']['orange'][1]
