C
The approach is more recent than RISC
D
Sequence of instructions are hard to pipeline
Explanation: 

Detailed explanation-1: -Explanation: CISC is a computer architecture where in the processor performs more complex operations in one step.

Detailed explanation-2: -Characteristic of CISC – Instructions are larger than one-word size. Instruction may take more than a single clock cycle to get executed. Less number of general-purpose registers as operations get performed in memory itself. Complex Addressing Modes.

Detailed explanation-3: -A computer in which individual instructions may perform many operations and take many cycles to execute, in contrast with reduced instruction set computer (RISC).
