hi,

see b.com (//b.com) regular and b.com (//b.com) professional both are undergraduate course, but the main difference is in the subjects, in b.com (//b.com) regular there is overall view of cost accounting, Economics, Management, Laws , taxation etc, whether in b,com professional there is many courses like soft skill, presentation making, rough idea of commerce is included. so if you want to do job just after graduation you should take b.com (//b.com) professional, but if you are interested for higher studies later,like CA, mba, m.com (//m.com) you should go for b.com (//b.com) regular course.
