Reporting OSAP Grant as a Full-Time Student

I am a full-time graduate student with a T2202A. I received an OSAP grant last year, and an accompanying T4A slip. 

In which Box 105 should I report the grant: the first option ("Full-time scholarship: also have T2202A with months in Box C") or the fifth option ("Other scholarships, grants, awards etc: taxable"). 

I have seen conflicting information online and on the forum. Any help would be appreciated. Thanks.
