Correct option is D
A person can be a mother, and also a teacher and/or a singer. These categories are not mutually exclusive, and they can overlap. Hence, the best representation is with three partially overlapping circles.
Explanation of options: (a) No overlap – Implies all three groups are completely unrelated, which is incorrect. (b) Touching circles – Suggests possible contact but no shared elements, which is too restrictive. (c) Fully overlapping – Suggests all mothers are teachers and singers, which is unrealistic. (d) Partially overlapping – This is the correct answer. It allows for people to belong to one, two, or all three categories.
