Beetle · Answer 1

Option D, from the same individual, but from different types of cells.

Explanation:

Given the identical DNA, it is likely that the samples were from the same individual as it is very unlikely for two different individuals to have the exact same DNA. It is more likely for the samples to be obtained from the cells of the same individual.

Given that different genes are expressed, it is likely that the DNA was obtained from different cells with different gene regulation mechanisms to express different genes and hence different proteins to perform different functions.
