    $options->getType(); // get option type

    $optionValues = $options->getValues();

    foreach($optionValues as $optVal)

$prdSku = 125; // sample sku  
$product = Mage::getModel('catalog/product');  
$prdId = $product->getIdBySku($prdSku);  
$product->load($prdId);  

if ($product->getId()) {  
  if ($product->hasCustomOptions()) {  
    foreach ($product->getOptions() as $opt) {  
      $optionType = $opt->getType();  

      if ($optionType == 'drop_down') {  
        $values = $opt->getValues();  

        foreach ($values as $k => $v) {  
          Mage::log("Array Key = $k;");  
          Mage::log("Array Value: $v");  
        }  
      }  
    }
