I truly think it's a mix of all three... but societies standards took my vote. Out of all of those, societies standards have the most influence on what we view as beautiful. But I have also seen people hate because of jealousy, and bully others. I had a friend in college who worked her ass off in the gym and started competing in body figure events. She looked smoking hott! She would workout in a sports bra and short shorts all the time. Women HATED her! They bashed her left and right. Said that her body was gross and manly. It was purely just jealousy . Hell if I had her body I would be flaunting it too!
