What is the product of all the numbers in the dial of a telephone?

Options

A. 1,59,480
B. 0
C. 1,59,450
D. 1,58,480

Explanation

To find the product of all the numbers on a telephone dial, we need to consider the numbers that are present on the dial. A standard telephone dial typically includes the following numbers:

1, 2, 3, 4, 5, 6, 7, 8, 9, and 0.

Now, let's calculate the product step by step:

### Step 1: Identify the numbers on the telephone dial
The numbers on a standard telephone dial are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

### Step 2: Understand the concept of product
The product of a set of numbers is obtained by multiplying all the numbers together.

### Step 3: Include all numbers in the product
We will multiply all the numbers from 0 to 9:
\[ 0 \times 1 \times 2 \times 3 \times 4 \times 5 \times 6 \times 7 \times 8 \times 9 \]

### Step 4: Recognize the effect of multiplying by zero
Since one of the numbers in this product is 0, any number multiplied by 0 results in 0. Therefore:
\[ 0 \times (any\ number) = 0 \]

### Step 5: Conclude the product
Thus, the product of all the numbers on the telephone dial is:
\[ 0 \]

### Final Answer:
The product of all the numbers in the dial of a telephone is **0**.
