Option (C) is correct.
"Register to-from memory with displacement" is not a type of instruction format.
About type of instruction format :
- In a one-byte instruction, the operator and operand are both in the same byte. Operands are internal registers that appear in the form of characters in the instruction.
- The Register-to-Register (RR) instructions conduct the stated actions on the machine's two fast registers and store the result in one of them.
- This instruction format includes one or two additional bytes for displacement, as well as a two-byte register to/from memory format with no displacement.
