Why is it necessary to take 3D scans of a diseased organ before a replacement organ can be created using stem cells? To find the organ's exact location within the body
To find the best injection site for the stem cells
To track the progress of the stem cells after they are injected into the diseased organ
To create a scaffolding for the stem cells while they recreate the diseased organ

B. is the correct option.

Explanation:

This is saying 3D SCAN, scans aren't recordings, they are essentially photos, so C. is incorrect. Stem cells don't need to rest on something while rescuing an organ, therefore D. is also improper. So, this leaves us with A. and B. B is the most proper because finding the best injection site you would need to find the organ's exact location, also.
