**Core Concept**
TB specific death rate is a measure of the number of deaths due to tuberculosis per 1000 population, it is an indicator of the severity of the disease in a community.

**Why the Correct Answer is Right**
To calculate TB specific death rate, we need to divide the number of deaths due to TB by the total population, and then multiply by 1000. In this case, the number of deaths due to TB is 30, and the total population is 6000. Therefore, the TB specific death rate is (30/6000) x 1000 = 5 per 1000 population.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not provide a valid calculation for TB specific death rate.
**Option B:** This option is incorrect because it is not a valid formula for calculating TB specific death rate. The correct formula is (number of deaths / total population) x 1000.
**Option C:** This option is incorrect because it does not provide a valid calculation for TB specific death rate. It seems to be a mix of the numerator and denominator.
**Option D:** This option is incorrect because it does not provide a valid calculation for TB specific death rate.

**Clinical Pearl / High-Yield Fact**
TB specific death rate is an important indicator of the effectiveness of TB control programs and the severity of the disease in a community. It can be used to monitor the progress of TB control efforts and identify areas where additional resources may be needed.

**Correct Answer: C. 5 per 1000 population**
