Best answer
Right option is (b) Condensed at the bottom of the column

The best explanation: The cracked vapours of the oil enters the fractionating column where the gasoline vapours and other gaseous products are recovered from the top, while the heavy gas oil fractions are condensed at the bottom of the column.
