B. 4050
C. 1
D. 7

Answer

To find the number of ways to arrange the 7 novels A, B, C, D, E, F, and G on Zafar's bookshelf, we can use the concept of permutations.

### Step-by-Step Solution:

1. **Identify the total number of novels**:
We have a total of 7 novels: A, B, C, D, E, F, and G.

2. **Understand the arrangement**:
We need to arrange all 7 novels in a specific order on the bookshelf.

3. **Use the factorial concept**:
The number of ways to arrange 'n' distinct items is given by 'n factorial' (n!). For our case, since we have 7 novels, we will calculate 7!.

4. **Calculate 7!**:
\[ 7! = 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 \]

5. **Perform the multiplication**:
- First, calculate \(7 \times 6 = 42\)
- Next, \(42 \times 5 = 210\)
- Then, \(210 \times 4 = 840\)
- After that, \(840 \times 3 = 2520\)
- Next, \(2520 \times 2 = 5040\)
- Finally, \(5040 \times 1 = 5040\)

6. **Conclusion**:
The total number of ways to arrange the 7 novels is 5040.

### Final Answer:
The number of ways in which Zafar can arrange all 7 novels on his bookshelf is **5040**.
