B It is typically more expensive to prepare than defined media due to reagent purity
C It often contains complex ingredients like yeast extract or peptones, with unknown exact composition
Correct Answer
D It exclusively supports the growth of eukaryotic cells, not prokaryotes
Correct Answer

Option C is the correct answer.

Detailed Explanation

An undefined (or complex) medium contains ingredients of unknown exact chemical composition, such as peptones (digests of proteins), yeast extract, or meat extract. These complex mixtures provide a rich, broad spectrum of nutrients suitable for many microorganisms, but their precise chemical makeup is not known.

Hint

The term 'undefined' refers to the exact chemical composition of the ingredients.
