Is ba is best for carrer or not

Your question is very ambiguous. What matters the most is whether or not it is right for you . If you are interested in subjects like Economics, Psychology, Sociology, Languages etc you should opt for a BA degree. There are many new upcoming fields in humanities and the scope is vast. The demand for humanities graduates is growing especially in the fields of economics and psychology. Also, you can take up a teaching job later or appear for Civil Services exam. Choose your subject carefully, keeping in mind your interest and aptitude. All the best!
