Correct Answer

A. एकैकीOne-one

Step 1

Concept

Assume (f(a)=f(b)).

Step 2

Why this answer is correct

From \(\frac{a+1}{2}=\frac{b+1}{2}\), we get (a+1=b+1), so (a=b).

Step 3

Exam Tip

A linear form with non-zero coefficient remains one-one. चरण 1: मान लें (f(a)=f(b))। चरण 2: \(\frac{a+1}{2}=\frac{b+1}{2}\) से (a+1=b+1), इसलिए (a=b)। चरण 3: शून्य से अलग गुणांक वाले रैखिक रूप में एकैकीता रहती है।
