To answer this question, let's analyze the options provided in relation to preload in a cardiac context.

1. **Understanding Preload**: Preload refers to the amount of stretch of the heart muscle prior to contraction, which is determined by the volume of blood in the ventricles at the end of diastole.

2. **Analyzing the Options**:
- **a. None of the above**: This option suggests that preload is not related to any of the other listed terms.
- **b. End Systolic Volume**: This is the volume of blood remaining in a ventricle after contraction (systole), which is not directly related to preload.
- **c. Afterload**: Afterload is the pressure the heart must work against to eject blood during systole, distinctly different from preload.
- **d. End Diastolic Volume**: This is the volume of blood in the ventricles at the end of diastole, which directly corresponds to preload since it determines the initial stretch of the heart muscle.

3. **Conclusion**: Based on the definitions above, preload is most closely associated with the End Diastolic Volume.

### Final Answer
**The correct answer is d. End Diastolic Volume.**
