Consider an $8085$ microprocessor system

The following program starts at location $0100 \mathrm{H}$.

$\begin{array}{l} \text{LXI SP, 00FF} \\ \text{LXI H, 0701} \\ \text{MVI A, 20H} \\ \text{SUB M} \end{array}$

The content of accumulator when the program counter reaches $0109 \mathrm{H}$ is

1. $20 \mathrm{H}$
2. $02 \mathrm{H}$
3. $00 \mathrm{H}$
4. $\mathrm{FFH}$
