The _____ instruction compares the immediate byte with the accumulator byte. (Write only the mnemonic and in ALL CAPS)

The mnemonic you are looking for is CMP.

In assembly language, the CMP (compare) instruction is commonly used to compare a value in a register (in this case, the accumulator) with an immediate byte or another value. This instruction effectively subtracts the immediate byte from the value in the accumulator but does not store the result; instead, it sets the flags in the status register based on the outcome of this operation. The flags will indicate whether the accumulator is less than, equal to, or greater than the immediate value, which can then be used for subsequent conditional branching or decision-making operations.
