It doesn't matter which branch you chooses it's matter how much effort you put in that field to learn if you want to clear upsc . In today's date most of the people are Engineer's who clear UPSC . If you are willing to do Engineering than choosing a core field may help you .  But if you don't want to waste enough money you can pursue a basic BSc or BA . UPSC exam doesn't deal with any field . It's an national level exam where you have to choose your subjects based on your bachelor field .  A BSc in a particular field is a good option it requires less time , less money and if you apply for BSc you can start your UPSC  preparation from first year. So, choose a good college to learn well in bachelor and sitting in a placement is also a good option you can prepare for UPSC with an earning in on side but this decisions depends on you .

Hope it will help you!!!
