Naswer is B and C

It support fixed length instruction. Not fewer instruction

It has less no addressing modes-- true

It has more register -- true

It is easier to implement using hardwired control logic -- False . Hradwired control logic is implemented inSOP form . Even a slight modification would require the whole circuit to redesign . It is faster but not easier

Option A: RISC only supports Register to register ALU operations, So as compared to CISC it has less Instruction set.(TRUE)

Option B: Because of limitation of using only Registers in ALU operations it has less Addressing Modes.(TRUE)

Option C: Because It has less Instruction Set to make circuits it takes less space, So more space for Registers as compared to CISC. (TRUE)

Option D: Less Instruction Set leads it easy to implement hardwired as compared to CISC.(TRUE)
