[Plugin: Woocommerce] Removing styling elements from cart

I am using Woocommerce plugin with Inspire theme from Woothemes. On my product page there’s few product variations for each product. After each variation attribute, it displays a horizontal line which looks ugly. I want to remove this horizontal line, but dont know where its code resides. I checked woocommerce/assets/css/woocommmerce.css and also theme’s css files but not yet successful in finding this thing. Can someone pls help me with it?

Refer the screenshot below to see the horizontal line I’m talking about. It looks like some kind of table border or probably an actual hr tag.
