Solution

The correct option is B A(2,3),B(4,4),C(6,7);
A′′(2,3),B′′(4,4),C′′(6,7)
When a point is reflected in the x axis, the sign of its ordinate changes. Hence, the coordinates of A,B,C are A(2,3),B(4,4),C(6,7) respectively.
When a point is reflected in the origin, the sign of its ordinate and abscissa both change. Hence, the coordinates of A",B",C" is the reflection of A,B,C in origin.
Coordinates of A",B",C" are A′′(2,3),B′′(4,4),C′′(6,7) respectively.
