Using tally marks, which one of the following represents the number eight:

Options

A.
B. `cancel(III)cancel(III)`
C. `cancel(IIIII)II`
D. `cancel(IIII)III`

Answer

To determine which of the given options represents the number eight using tally marks, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Tally Marks Representation**:
- Tally marks are used to represent numbers in groups of five.
- The first four marks are drawn as vertical lines (|), and the fifth mark is drawn as a diagonal line crossing the first four (like a slash).

2. **Count the Tally Marks**:
- To represent the number eight, we need to count the tally marks correctly.
- The first five marks will be represented as four vertical lines and one diagonal line (which represents 5).
- For the next three marks, we will add three more vertical lines.

3. **Constructing the Tally Marks for Eight**:
- So, for the number 8, the tally marks will look like this:
- First five: | | | | (4 vertical lines) and then a diagonal line to represent 5: \
- Next three: | | | (3 additional vertical lines)
- Therefore, the complete representation for 8 will be:
- | | | | (4) \
- (5) \
- | | | (6, 7, 8)

4. **Identify the Correct Option**:
- Now, we need to look at the options provided and see which one matches this representation.
- The correct option should have four vertical lines followed by a diagonal line and then three more vertical lines.

5. **Final Answer**:
- After checking all the options, the one that correctly represents the number 8 using tally marks is **Option 4**.
