Hello student. Hindi as a subject in your class 12th is not related with you taking any of the subjects that are mentioned above as optional ones. First, find and know where your interest lies in. Computer science, biology and vocational subjects are there different paths. Computer science is more related to IT field technology etc, biology is a different stream with plants and animals, whereas vocational subjects develop practical skills in many areas. Som see where your interest lies in, and hindi being your class 12th doesn't affect  whichever subject you take now.
All the best
