Study the following family tree carefully and answer the question given below.…

Concept: In a family-tree diagram, an oval node stands for a female member and a rectangle node stands for a male member; a horizontal connector between two nodes marks a marriage, and a vertical line dropping from that connector marks their children. When a person's name is drawn without either shape, the diagram simply does not fix that person's gender, so any total that depends on them cannot be pinned to one value.

Application: Reading every node in the tree against this convention gives:

Every family member listed above is drawn as either an oval or a rectangle, except Suman, who is written under Umesh and Geeta with only a connecting line and no shape at all. Counting only the members clearly drawn as an oval gives 5 (Sweetie, Chaarvi, Kajal, Geeta, Aisha).

Cross-check: Because Suman carries no oval or rectangle, both readings are equally consistent with the diagram as drawn - taking Suman as female gives a total of 6, and taking Suman as male gives a total of 5. Neither reading is favoured by any mark in the diagram, so the diagram alone does not fix a single total.

Result: Since the given information supports more than one possible count, the total number of females in the family cannot be determined.
