b is the right option if he doesn't do anything with his asset? we can't reach any 2nd period consumption given in the other options after taking into account the respective first period consumptions.
Maximum he can consume in current period is = 42000 + 18000 + (33000/1.1) = 90000
Maximum he can consume in future period is = (42000 + 18000)(1.1) + 33000 = 99000
if we are required to tell the maximum consumption level then we will take the two extreme cases i.e. s/he is consuming her entire two periods income in one period only?
