A kite shaped card-board is rotated about its line of symmetry (shown by dotted line). The solid figure so obtained has :
(i) one cone formed
(ii) two cones formed
(iii) three cones formed
only (ii)
only (iii)
both (i) and (iii)
neither (i) nor (iii)

Answer

When the kite shaped card-board is rotated about line of symmetry then three cones are formed, two from the square shaped part and one from the triangle shaped part.

Hence, Option 2 is the correct option.
