Hi,
Bba is more closely aligned with the sciences than humanities. All degrees will educate student on a variety of subjects, but the courses leading to a bba are more specialized and the increased focus isn't on the humanities . So it will be my advice to pursue ba as it has more career options and it will make more sense for a humanities student to pursue it .
But at last it's your choice based upon your interests as both are equally good degrees , whether you pursue ba or bba just focus to be at the top to get good placements.
Hope it helps
