Answer this for me mate. Much appreciated.

**Question:**

How much of the parent isotope and daughter product exists after 1 half-life?

- ○ 100%
- ○ 75%
- ○ 50%
- ○ 25%

**Graph Explanation:**

The graph, titled "Half-life of Element X," illustrates the decay of a radioactive element over time. The y-axis represents the "mass of Element X" expressed in percentage, while the x-axis represents the "number of half-lives."

The graph starts at 100% mass at 0 half-lives. It shows an exponential decay curve as follows:
- After 1 half-life, the mass of Element X reduces to approximately 50%.
- The curve continues to decrease by half for each successive half-life, indicating the exponential nature of radioactive decay.
