Grouping Exposed Filters (using Better Exposed Filters)
First I'd recommend adding a taxonomy term 'Graduate Interdisciplinary Program' to match the 'Undergraduate Interdisciplinary Program'

Assuming you have these taxonomy terms 'weighted' to their respective parent terms 'Graduate' and 'Undergraduate' you can proceed to configure your view.

Configure the filter criteria as follows:

Settings
Content:Has Taxonomy Terms
Vocabulary: Graduate/Undergraduate Programs
Selection Type: Dropdown
Depth: 1



Configure Filter Criteria
Tick - Expose this filter to Visitors, to allow them to change it.
Tick - Grouped Filters
Widget Type - Select List
Label - 'Area of Study'


Finally configure the table as you have it in your screen-shot ... ideally without the overlap of the term 'Multidisciplinary Program' ...
