**Core Concept**
Selective media are used to isolate and grow specific microorganisms by inhibiting the growth of other bacteria. Vibrio cholerae, the causative agent of cholera, requires a specific type of selective media to grow in the laboratory.
**Why the Correct Answer is Right**
The correct answer is Alkaline Peptone Water (APW). APW is a selective media that allows Vibrio cholerae to grow while inhibiting the growth of other bacteria. This is because APW has a pH range of 8.6-9.4, which is optimal for Vibrio cholerae growth, and also contains peptones that provide a carbon source for the bacteria. Vibrio cholerae has a specific requirement for alkaline conditions to grow, which is met by APW.
**Why Each Wrong Option is Incorrect**
**Option A:** Thiosulfate-citrate-bile salts-sucrose agar (TCBS) is a selective media for Vibrio species, but it is not the primary selective media for Vibrio cholerae.
**Option B:** Deoxycholate agar is a selective media for Gram-negative bacteria, but it is not specific for Vibrio cholerae.
**Option C:** MacConkey agar is a selective media for lactose-fermenting Gram-negative bacteria, which does not include Vibrio cholerae.
**Clinical Pearl / High-Yield Fact**
Remember that Vibrio cholerae requires alkaline conditions to grow, which is a key characteristic used in its identification and isolation.
**Correct Answer:** C.
