Correct Answer

A. 1 न अभाज्य है और न संयुक्त1 is neither prime nor composite

Step 1

Concept

A prime number must have exactly two positive factors.

Step 2

Why this answer is correct

1 has only one positive factor, so it is not prime.

Step 3

Exam Tip

A composite number needs more than two factors, so 1 is not composite either. चरण 1: अभाज्य संख्या के ठीक दो धनात्मक भाजक होने चाहिए। चरण 2: 1 का केवल एक धनात्मक भाजक है, इसलिए वह अभाज्य नहीं है। चरण 3: संयुक्त संख्या के भी दो से अधिक भाजक चाहिए, इसलिए 1 संयुक्त भी नहीं है।
