Drupal 7 - Populate Drop Down select from DB in Form API - drupal-7

Question

I am still new to PHP, and even newer to Drupal's Form API. I'm simply trying to populate a drop down select from the database. I think the issue stems from my lack of a deep understanding of how to work with multidimensional arrays. Any help is sincerely appreciated.
My code is currently:
//Query DB for Rows
$query = db_select('hp_education_years');
$query->fields('hp_education_years', array('id', 'years',));
$query->orderBy('years', 'ASC');
$results = $query->execute();
//define rows
$options = array();
foreach ($results as $result) {
$options[$result->id] = array(
$result->years,
);
}
$form['education']['year'] = array(
'#type' => 'select',
'#title' => t('Year'),
'#options' => $options,
'#states' => array(
'visible' => array(
':input[name="data_set"]' => array('value' => 'education'),
),
),
);
This returned a populated list, but displays the year's ID in bold as well as the year (2008 for example).
How can I get the dropdown just to display the year, not the year ID in bold, and then the year. It seems like $option is just a level higher than I want it to be? if that makes sense?
Many thanks in advance.

Try changing
//define rows
$options = array();
foreach ($results as $result) {
$options[$result->id] = array(
$result->years,
);
}
to
//define rows
$options = array();
foreach ($results as $result) {
$options[$result->id] = $result->years;
}
If you look at the example from Drupal's Form API, you'll see that the Options values should be just the string value and not an array.
