Sanjoy, Code 02 is for those Candidates who have completed their 12th in 2019 and they haven't joined any other course. In a way there are freshers. So code 02 is not fo you because you have joined B.Pharamcy. Code 05 is for the students who are studying 1st year of 3 year B.Sc course. It is not applicable for you because you are 2nd year of B.Pharmacy. Now that you do not fit in both the categories, your code will be 07. Code 07 says:

Any other examination which in scope and standard (Last 02 years of 10+2 Study comprising of Physics, Chemistry and Biology/Bio-technology; which shall include practical test in these subjects) is found to be equivalent to the Intermediate Science Examination of an Indian University/Board, taking Physics, Chemistry and Biology/Biotechnology including practical tests in each of these subjects and English.
