Cabinet, Home Minister, Minister.

a
b
c
d
The relationship between "Cabinet," "Home Minister," and "Minister" is that the Home Minister is a type of Minister, and the Cabinet consists of Ministers. Thus, the correct diagram is two circles representing Ministers and Home Ministers with overlap, similar to option (b).
Work out the logical containment relationship between the three terms first, then match it to a diagram type rather than describing any single figure.
Hence, three concentric circles, one inside the other, correctly represents Cabinet, Home Minister and Minister, which is option (b).
