**Core Concept**
Typhoid carriers are individuals who harbor the bacteria Salmonella Typhi in their bodies, often without symptoms, and can spread the disease to others. The carrier state can persist for years and is a significant public health concern.

**Why the Correct Answer is Right**
Male carriers of typhoid are indeed less common than female carriers, but they are more likely to be the source of outbreaks due to their higher bacterial loads and more frequent shedding of the bacteria. This is because male carriers tend to have a higher concentration of bacteria in their gallbladders, which can lead to increased shedding and transmission to others. In contrast, female carriers often have a lower bacterial load and are less likely to transmit the disease.

**Why Each Wrong Option is Incorrect**
**Option A:** This statement is incorrect because female carriers are actually more common than male carriers. Studies have shown that up to 95% of typhoid carriers are female.
**Option C:** This statement is incorrect because the gallbladder is often involved in the carrier state. The bacteria can colonize the gallbladder and remain there for years, even after the patient has recovered from the acute illness.
**Option D:** This statement is incorrect because the drug of choice (DOC) for typhoid carriers is actually ciprofloxacin, not tetracycline. Ciprofloxacin is effective in eradicating the bacteria from the gallbladder and preventing transmission.

**Clinical Pearl / High-Yield Fact**
Typhoid carriers can be identified through stool culture and are often asymptomatic. The bacteria can be eradicated with antibiotics, but relapse can occur if the gallbladder is not treated.

**✓ Correct Answer: B. Male carriers though less are more dangerous**
