Correct Answer

B. 9

Step 1

Concept

The remainder must satisfy \(0\le r<9\).

Step 2

Why this answer is correct

The possible values are 0 through 8, so there are 9 values.

Step 3

Exam Tip

The number of possible remainders is equal to the divisor. चरण 1: शेषफल के लिए \(0\le r<9\) होगा। चरण 2: संभव मान 0, 1, 2, 3, 4, 5, 6, 7, 8 हैं, कुल 9 मान। चरण 3: संभव शेषफलों की संख्या हमेशा भाजक के बराबर होती है।
