Continue from the last question, now we will also handle Linear Equation $($i$.$e$.,$ a is zero$).$

Below are the correct and wrong solutions from Mary and Peter. Which of the following

statements is$/$are True?

$($Choose All correct answer$($s$).$ Note: At least one of them is correct.$)$

When $a$ is zero but $d$ is not close to zero, Peter's program will give wrong result.

When $a$ is non$-$zero but $d$ is close to zero, Peter's program will give wrong result.
