3. (3 pts) Determine which MIPS assembly instruction(s) if any, that we discussed in class (R-format (including add, sub, or, and, nor, slt), lw, sw, beq, j) will not work correctly and explain what will happen instead, if each of the following control signals in the single-cycle datapath that we saw in class (shown below) is always stuck at one value specified below:

a). MemWrite = 1 (always stuck at 1)

b). ALUSrc = 1 (always stuck at 1)

c). RegWrite = 1 (always stuck at 1)
