US UK TAX TREATY w-8ben form

Hi, I am a full-time PhD Student from Staffordshire University, UK. I have applied for an expense grant from the Institute for Humane Studies, George Mason University, USA. This is a funding grant, they provide to support students based on merit. I have been successful in my grant application and they are processing my payment. However, they asked me to fill w-8ben form (Individual). I need help in filling the part 2 of this w-8ben form which is about tax treaty and I need to mention under which article my income will be taxable or receive an exemption. I spoke to the funder they said it is taxable income in the US but I am not sure because in the UK fellowships and scholarships are tax-free but in the US it is not I guess. Please help me with the same. I am not a British citizen and I am from India on a student visa but I am a UK tax resident. Please help me if you can.

Hi US UK TAX TREATY w-8ben form,
The form you refer to is an American form and you need to contact the US authorities on how to complete it.
Thank you.
