As per IS:456, Removal of formwork for vertical columns is between 16-24 hrs.

Minimum 10hours for vertical side columns but curing is regular 2 time/day, so 14 days.

Option D wasn't correct because all vertical form work of column, wall and beams should be removed within 16-24 hours.

21 days is enough of durability for concrete.
