Correct Answer

A. एकैकीOne-one

Step 1

Concept

The outputs of the four inputs are (8,7,6,5).

Step 2

Why this answer is correct

No output is repeated.

Step 3

Exam Tip

Reverse order does not matter; if outputs are different, the function is one-one. चरण 1: चार निवेशों के निर्गत (8,7,6,5) हैं। चरण 2: कोई निर्गत दोहराया नहीं गया है। चरण 3: क्रम उल्टा होने से फर्क नहीं पड़ता; निर्गत अलग हों तो फलन एकैकी है।
