There are two classes of three figures each. Class 'A' figures differ in certain way from figures in Class 'B'. Which two of the four answer figures belong to Class 'A'?

From the first figure to the second figure the middle design rotates through 90° and moves to the extreme right position after being reduced in size and the lower most design encloses the inverted and reduced upper most design.

From first figure to second figure the middle design becomes shaded, the left design moves to the bottom after being rotated through 90° clockwise and the right design moves to the top after being rotated through 90° anticlockwise.

From first figure to second figure the design rotates through 180° and three circles are added at its ends.

From first figure to second figure the outer design is deleted and the other three designs are arranged vertically: the left design on the top and the right design in the middle.

From first figure to second figure to the left of sign (::), one leaflet is deleted and one line segment is added in each of the leaflets.

Figures 2 and 4 are identical.

From first figure to second, one side of the main design is deleted and the inner circles move out of the main design and the outer circle moves inside the main design.

From first figure to second figure an inverted figure is also added.

From first figure to second figure one small triangle is added. Similarly, one small circle would be added in the figure given to the right side of sign (::).

From first figure to second figure the main design rotates through 45° anticlockwise and the arrow moves half step in anticlockwise direction.
