The correct option is C Both 1 and 3
The lines of symmetry is the line that will divide the figure into two halves in such a way that one will be a mirror image of the other one.
We will try to check the two halves of the image. If they are mirror images or after folding the shape across the line it will overlap the other part completely, then it will be a line of symmetry.
=> Line 1: Circle and arrow One half is a completely mirrored image of the other half. It is a line of symmetry.
=> Line 2: Triangle and cloud One half is not overlapping the other half if we fold the paper across the line. It is not a line of symmetry.
=> Line 3: Heart and Star One half is overlapping the other half. It is the line of symmetry.
Hence, we have two lines of symmetry which are Line 1 and Line 3
