Apply for B2, though they give B1/B2 combined but you have to justify the first visit during the interview with the consulate officer. If you pitch in the thought about business visit in the future, be ready for serious questioning you might be uncomfortable answering.

Just apply for the B2. Explain that you just want to travel for tourism and are visiting friends.
The officer at the embassy will decide if you qualify for B2 or B1/B2; 9/10 if you apply for B2 or B1, you get B1/B2.
Don't apply for B1/B2 and then in the interview say "in case in the future..." this is surely going to get you rejected.
