When coding in LC-3, there are many ways to check that two registers (say R1 and R2) values are equal. Which statement below is true?

Your answer:
	You use the AND instruction between the two registers. The outcome is 1 if they are equal and 0 otherwise. From there you use a simple conditional branch instruction
	You use the Division instruction DIV between register R1 and R2. If the outcome is 1 then they are equal. From there you use a simple conditional branch instruction
	You store their difference in a register and compare the register content to zero using the BRz instruction
	You use the CR (Compare Register) instruction which directly compares two register values
