Challenge #1 of 1

Q:
What's the significance of using the `fetch()` method instead of `fetchAll()` with the following query (which will always match exactly 1 or 0 rows):

`SELECT * FROM product WHERE id = 1`

fetch() fetches a single row, while fetchAll() fetches the single row wrapped in an array.

fetch() fetches a single row, while fetchAll() fetches all rows.

There is no difference between fetch() and fetchAll() when querying for a single row.

fetch() fetches rows in a random order, while fetchAll() fetches them sequentially.
