High pressure fluid in a shell and tube heat exchanger should preferably be routed through the

A Tubes to avoid the expansion of high pressure shell construction
B Shell side for smaller total pressure drop
C Shell side, if the flow is counter-current and tube side if the flow is co-current
D Shell side for large overall heat transfer co-efficient
