Load-reduced DIMMs (LRDIMMs) is memory that is designed to increase system memory capacity and speed. Like a registered DIMM (RDIMM), LRDIMMs buffer the address and control signals. Unlike an RDIMM, an LRDIMM also buffers the data lines. In an RDIMM, data signals are driven by a controller, limiting performance. Not only do LRDIMMs improve performance, they also reduce problems associated with heat and power dissipation.
It is a tricky question … but since it’s comparing LRDIMM to RDIMM i would say that the right answer is
B

LRDIMM is a load-reduction (LR) DIMM (used in servers) that supports higher densities than RDIMMs and contains a memory buffer (MB) chip, as opposed to a register, in order to reduce and minimize the load on the server memory bus.
