B.Sc. Nursing is the best for you. Nursing course have the best employment opportunities over other courses if done from a reputed Institutes. Hence prefer to do B.Sc. Nursing.

B.Sc Micro and Bio chemistry courses are common and there are many colleges that offer these courses. But agricultural engineering is a rare branch , only few institutions conduct this course. So its more demanding course than Bio chemistry and Microbiology
Agricultural engineers have opportunities in agricultural research centers, universities , large scale nurseries, plantations etc.

All the BSc Programs are good having wide range of job opportunities after MSc program in the same. Say you want to be an Microbiologist, you can opt for BSc Microbiology. BSc Biological Science, Botany, Zoology, Biochemistry are non clinical subjects whereas Microbiology and Medical Science have clinical applications.
