Match the corresponding entries of column \(I\)  with column \(II\). [Where \(m\) is the magnification produced by the mirror]  \(\begin{array}{|l|l|} \hline Column\,\,-I  & Column\,\,-\,\,II\,\, \\ \hline 1.\,\,m=-2  & a.\,\,Convex\,\,mirror \\ \hline 2.\,\,m=\,\,\frac{-1}{2} & b.\,\,Concave\,\,mirror \\ \hline 3.\,\,m=+2  & c.\,\,Real\,\,Image \\ \hline 4.\,\,m=\,\,\frac{+1}{2} & d.\,\,Virtual\,\,image \\ \hline \end{array}\)

1. A \((1-a \) and \( c),(2-a\)  and  \( d),(3-a \) and \(b) (4-c\) and \(d)\)
2. B \((1-a\) and \(d),(2-b \) and \(c),(3-b\) and \( d) (4-b\) and \(c)\)
3. C \((1-c \) and \(d),(2-b\) and \(d),(3-b\) and \(c) (4-a \) and \( d)\)
4. D \((1-b\) and \(c),(2-b\) and \(c),(3-b\) and \(d) (4-a\) and \(d)\)
