randomize default variable

Look,
product “bag” has three options:

-please choose an option
-option A
-option B
-option C

i want to hide the choose and option and choose one of these options as default (available in stock)

there is code but it has problem(problem is that the array contains the out of stock options too):

add_filter('woocommerce_dropdown_variation_attribute_options_args','fun_select_default_option',10,1);
function fun_select_default_option( $args)
{
    if(count($args['options']) > 0)
        $args['selected'] = $args['options'][0];
}

if the option A be out of stock , this array doesnt work because option A is the first value of array($args[‘options’][0]).

if you can somehow add filter that array has the in stock options.

thank you
