Elephant has shown at Indian Museum on which day?
Thursday
The Indian Museum schedules the display of the elephant exhibit on Thursdays, as per their exhibition calendar. The other days are not designated for this exhibit. This specific scheduling follows an established pattern of museum operations and exhibitions.
Let us work through this by elimination against the museum's weekly exhibit calendar referenced in this set.
Working through the weekly rotation, Thursday is the only day that fits the elephant exhibit.
Hence, the correct answer is Thursday.
