Correct Answer

B. (f) एकैकी नहीं है(f) is not one-one

Step 1

Concept

(3) and (5) are different inputs.

Step 2

Why this answer is correct

Both have image (8).

Step 3

Exam Tip

The same image for different inputs is direct proof against one-one nature. चरण 1: (3) और (5) अलग-अलग आगत हैं। चरण 2: दोनों की छवि (8) है। चरण 3: अलग आगतों की समान छवि एकैकीता के विरुद्ध सीधा प्रमाण है।
