Hello Sheetal,
If you are clear about what you are going to pursue after bachelor's then B.Sc. Honours in your desired subject otherwise do B.Sc. General. It will give you more precise insight for M.Sc.
Otherwise, If you have aspirations for any particular sector then you should go accordingly. Suppose you want to go in chemical Industry sector or Pharma then you should go for B.Sc. Chemistry Hons.

GOOD luck.
