Two main reasons:
1 - Steam condensate has dissolved CO2 & O2 which causes corrosion and tube side is less costly to get replaced.
2 - If we send hot condensate in the shell side we have to use insulation as it is directly exposed to ambient.

Option B is the right answer. Steam condensate has less tendency of fouling than process stream fluid.
So steam condensate must be passed through the shell side.
