B. conductance
C. resistivity
D. conductivity

Answer

To solve the question regarding the slope of the current against voltage curve in Ohm's law, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ohm's Law**:
Ohm's law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it. This can be mathematically expressed as:
\[ V = R \cdot I \]
where \( R \) is the resistance of the conductor.

2. **Graphing Voltage vs. Current**:
When we plot a graph with voltage (V) on the y-axis and current (I) on the x-axis, we can observe the relationship dictated by Ohm's law.

3. **Identifying the Slope**:
The slope of a line in a graph is defined as the change in the y-axis value divided by the change in the x-axis value. For our graph:
\[ \text{slope} = \frac{\Delta V}{\Delta I} \]

4. **Relating Slope to Resistance**:
From Ohm's law, we can rearrange the equation to express resistance as:
\[ R = \frac{V}{I} \]
This indicates that the slope of the V-I graph (which is \( \frac{V}{I} \)) is equal to the resistance \( R \).

5. **Conclusion**:
Therefore, the slope of the current against voltage curve in Ohm's law represents the resistance of the conductor.

### Final Answer:
The slope gives **Resistance (R)**.
