Of the following isomers of C 9 H 20 , which is the most stable?

The most stable isomer would have minimal steric hindrance, which is determined by the orientation of its substituents. The isomer 2,2,3,4-tetramethylpentane has the most branched structure, which reduces steric hindrance and makes it the most stable.
