Stem-cell therapies aim to regenerate damaged tissues and organs, which can reduce the demand for donor transplants and therefore shorten transplant waiting lists — this is the central idea that supports option D.

1. Relevant knowledge points and concepts
- Stem cells have the capacity to differentiate into specialized cell types and to repair or replace damaged tissue.
- If medical treatments restore organ function using a patient’s own or lab-grown cells, fewer patients will require donor organs.
- The author’s likely stance in the passage would be based on these medical and practical consequences rather than on unrelated or speculative claims.

2. Step-by-step reasoning
- Premise: Stem-cell treatments can regenerate or repair damaged organs.
- Consequence: Successful regeneration reduces the need for organ replacement via transplantation.
- Result: A lower demand for donor organs would reduce pressure on transplant waiting lists.
- Therefore, the author who emphasizes the regenerative potential of stem cells would most probably agree with the statement that these treatments are reducing transplant waiting lists.

3. Calculations
- No numerical calculations are required; the logic follows cause (regeneration) → effect (fewer transplants needed) → outcome (reduced waiting lists).

4. Why the correct answer is correct
- Option D directly connects the medical capability of stem cells (repairing organs) to an observable systemic effect (shorter or reduced transplant waiting lists). This is a moderate, evidence-based inference consistent with an author discussing practical benefits of stem-cell therapy.

5. Why the other options are incorrect
- A: “Most useful for builders” is unrelated and literal; it misinterprets “builders” and is not supported by medical discussion.
- B: “Lives that are extended will also be improved” is speculative; life extension does not automatically imply improved quality, and the author would not necessarily claim both together.
- C: “Restored brain cells to repair heart tissue” mixes organ-specific biology in an implausible way; the statement is scientifically unlikely and not a reasonable inference.

6. Conclusion
All reasoning supports option D. Confirming final answer: d. Stem cell treatments are reducing transplant waiting lists.
