What assembly language instruction clears register $25 ?

or  $25,$0,$0        # $25 <-- $0

(There are others that also work for this).

Target Instruction

The program starts with:

or  $25,$0,$0        # clear $25

Now the correct bit patterns are placed into the fields of the instruction. The instruction we are assembling is:

ori  $8,$9,0x004A

Fill in the fourth row with the bit patterns. Use hexadecimal (assume that the bit patterns are truncated on the left to make them the right size).
