Answer:
Option D
Explanation:
- From the picture, we can see two types of bacteria (i.e. A and B), therefore it is not a pure culture.
- We can not predict whether any culture has been lost during incubation.
- A and B are different organisms.
Hence, the only correct option is D, which states:
"Identification of microbial types in the environmental sample could have been attempted without culturing anything."
