I'm going with D) false. The array_merge function returns a new array, so $a[2] will not be defined, resulting in a false value.

The correct answer is C) 2. The + operator will merge the arrays, but it will preserve the keys from the second array, so the element at index 2 will be 2.

I think the answer is B) 3. The array_merge function will combine the two arrays, and the element at index 2 will be 3 from the first array.

I'm not sure, but I think it might be a parse error.
