Correct Answer

A. एकैकी हैOne-one

Step 1

Concept

Every input has exactly one output.

Step 2

Why this answer is correct

The outputs (b,c,a) are all distinct, so no two inputs have the same output.

Step 3

Exam Tip

For finite sets, checking repeated outputs quickly identifies one-one behavior. चरण 1: हर आगत का केवल एक निर्गत है। चरण 2: निर्गत (b,c,a) अलग-अलग हैं, इसलिए कोई दो आगत समान निर्गत नहीं देते। चरण 3: सीमित समुच्चय में निर्गतों की पुनरावृत्ति देखकर एकैकी जल्दी पहचाना जा सकता है।
