Step 1: Understanding the Question:
We need to match the word groups in Column-I to their logical representation using Venn diagrams in Column-II.
Step 2: Detailed Explanation:
Let us analyze each group individually:
-
(a) Women, Mothers, Widows:
All mothers are women, and all widows are women. Some mothers are also widows, and some widows are mothers. Thus, both "Mothers" and "Widows" circles must reside completely inside the larger "Women" circle and must intersect each other. This is represented by diagram (IV). Thus, a-IV.
-
(b) Authors, Teachers, Men:
Some authors are teachers, some teachers are men, and some men are authors. There are also individuals who are authors, teachers, and men simultaneously. This is represented by three mutually intersecting circles, which is diagram (I). Thus, b-I.
-
(c) Sparrows, Birds, Mice:
All sparrows are birds, so the "Sparrows" circle is completely inside the "Birds" circle. Mice are mammals and are completely separate from birds. This is represented by a circle inside a circle with a separate external circle, which is diagram (II). Thus, c-II.
-
(d) Tea, Coffee, Beverages:
Both tea and coffee are types of beverages, so both circles are completely inside the "Beverages" circle. However, tea and coffee are entirely distinct from each other and do not intersect. This is represented by one large circle containing two separate smaller circles, which is diagram (III). Thus, d-III.
Comparing this matching (a-IV, b-I, c-II, d-III) with the options, it corresponds to Option (A).
Step 3: Final Answer:
(A) a-IV, b-I, c-II, d-III
