Solution
The compound has two chiral centers (carbon atoms with four different groups). For n chiral centers, maximum stereoisomers are 2n. Here n=2, so maximum is 4. The molecule is symmetric, but the ring structure does not create a meso compound or identical isomers. Therefore, all 4 stereoisomers are distinct: (R,R), (R,S), (S,R), and (S,S).
Final answer: 4
