Step 1: Recall the distance formula.
The distance between two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by:
\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Step 2: Substitute the given values.
Here, $(x_1, y_1) = (0, 0)$ and $(x_2, y_2) = (3, 4)$
\[
d = \sqrt{(3 - 0)^2 + (4 - 0)^2} = \sqrt{9 + 16} = \sqrt{25}
\]
Step 3: Simplify.
\[
d = 5
\]
Step 4: Conclusion.
Hence, the distance between the two points is 5 units.
Correct Answer: 5 units
