Conceptual MIPS Questions

The choices displayed were my guesses which were graded as incorrect.

Which of the following are false statements about the instruction set of the MIPS processor? O The immediate field in an ALUi instruction is always extended to 32 bits by adding 16 1s in the high order positions. O The Op. Code field is 6 bits long and as a result, the MIPS instruction set includes 64 instructions O All MIPS instructions use all the 32 bits in their format. O The offset field in conditional branch instructions is signed extended before being added Which of the following are false statements about the instruction set of the MIPS processor?
