get_field_object requires the field key if you are not referencing a saved value. The field key looks something like: field_53beaa2f69615
In the Edit Field Group screen:
Screen Options (window shade) > Show Field Key: Yes
One you have it:
$field = get_field_object($field_key);
echo $field['choices']['fr'];
foreach( $field['choices'] as $name => $label ) { ... }
