Correct Answer

A. ((z,z))

Step 1

Concept

The elements (x,y,z) need their self-pairs.

Step 2

Why this answer is correct

((x,x)) and ((y,y)) are present, but ((z,z)) is missing.

Step 3

Exam Tip

Add the missing self-pair of the missing element. चरण 1: (x,y,z) के अपने-अपने युग्म होने चाहिए। चरण 2: ((x,x)) और ((y,y)) हैं, लेकिन ((z,z)) नहीं है। चरण 3: छूटे हुए तत्व का अपना युग्म जोड़ना सबसे सीधा तरीका है।
