1. All of these are isolating factors for South Asia EXCEPT:* Hindu Kush Mountains
The Arabian Sea
The Bay of Bengal
The monsoons

Hindu Kush Mountains

Explanation:

These mountains are located in the Middle East, not South Asia. The Arabian Sea is to the direct east of India. The Bay of Bengal is to the direct west of India. Monsoons are an ongoing environment issue, which can come from all sides. Therefore, Hindu Kish Mountains cannot count as an isolating factor for South Asia.
