Explanation:

To solve this, we analyze each option:

• Option A: Totipotent cells can give rise to placental cells and all cell types, while pluripotent cells (like embryonic stem cells) can differentiate into all cell types of the embryo but not placental cells. This matches the difference.
• Option B: Pluripotent cells don't disappear after birth; there are other stem cells, so this is incorrect.
• Option C: Pluripotent cells (e.g., in research) can be used in both adults and children, so this is wrong.
• Option D: Pluripotent cells can differentiate into multiple cell types (not just one), so this is incorrect.

Answer:

A. Pluripotent cells can't give rise to placental cells.
