Correct Answer

A. (r=8)

Step 1

Concept

For degree (0), both variable terms must vanish. From (r-8=0), we get (r=8).

Step 2

Why this answer is correct

The correct answer is A. (r=8). For degree (0), both variable terms must vanish. From (r-8=0), we get (r=8).

Step 3

Exam Tip

डिग्री (0) के लिए दोनों चर पद हटने चाहिए। (r-8=0) से (r=8) मिलता है।
