Drop Down options aren’t saving in my wordpress plugin options page

So, I’m developing a plugin. I have an options page with tabs, and so far so good. The text and text area settings are working OK, but the drop down options aren’t saving. For reasons I don’t know. Here’s the code:

The HTML renders as follows:

<select name='dropdown_settings[select_field_0]'>
    <option value='1' <?php selected( $options['select_field_0'], 1 ); ?>>INFO</option>
    <option value='2' <?php selected( $options['select_field_0'], 2 ); ?>>SDAMZUMBE</option>
    <option value='3' <?php selected( $options['select_field_0'], 3 ); ?>>CHANGARAWE</option>
</select>

What could I be doing wrong. (The options appear as desired, but when I click the “Submit” button it renders the first element by default).
