taking each option and drawing hash table is not fastest approach
option elimination will be correct approach here
by looking at given hash table we draw following conclusion
1) 52 must come after 42 , hence sequence is 42 , 52
2)33 must come after 33 hence sequence is 23 ,33
3)52 must come after 23 & 34 . note that order between 23 and 34 does not matter
4)33 must come after 34 52 & 46 note that order between this three number does not matter
now check each option , you will find c is correct
