Correct Answer

C. (9)

Step 1

Concept

Putting (c=-12) gives (m-(-12)=21). So (m+12=21) and (m=9).

Step 2

Why this answer is correct

The correct answer is C. (9). Putting (c=-12) gives (m-(-12)=21). So (m+12=21) and (m=9).

Step 3

Exam Tip

(c=-12) रखने पर (m-(-12)=21) मिलता है। इसलिए (m+12=21) और (m=9) है।
