C)coarse-grained multithreading
D)chip multiprocessing

SMT stands for Simultaneous Multithreading, which allows multiple threads to issue instructions simultaneously to the execution units of a superscalar processor. This technique improves the efficiency of the processor by keeping the execution units busy with instructions from multiple threads. Single-threaded scalar and coarse-grained multithreading are not relevant to this concept, while chip multiprocessing is a separate technique that involves the use of multiple processors on a single chip. Therefore, the best choice for this concept is SMT.
