**Question:** Bullet that fragments on impact is called: Kerala 06

**Core Concept:** Bulletproof vests were initially designed to protect against large caliber rifle rounds, which are capable of penetrating human skin and causing significant tissue damage. However, as the use of handguns increased, there was a need for protection against smaller caliber rounds that could still cause serious injuries despite not penetrating the vest. The term "Kerala 06" refers to a specific type of small caliber bullet that is designed to fragment upon impact, increasing the area of injury and making it more effective in causing damage to the victim.

**Why the Correct Answer is Right:** A bullet fragmenting upon impact is known as a "fragmenting bullet" or "tumbling bullet." Kerala 06 is a specific type of fragmenting bullet, designed to break apart upon entering the body, and hence, the correct answer.

**Why Each Wrong Option is Incorrect:**

A. **Kerala 05**: This is not a correct term as per the question. The correct term is "Kerala 06."

B. **Non-fragmenting bullet**: A non-fragmenting bullet does not break apart upon impact, which is the opposite of the concept being tested in this question.

C. **Non-Kerala bullet**: The question specifically mentions "Kerala 06," indicating that the correct answer should include this term.

D. **Unrelated term**: This option contains an unrelated term that does not address the concept of a bullet fragmenting upon impact, which is the main focus of the question.

**Clinical Pearl / High-Yield Fact:** The use of fragmenting bullets like Kerala 06 is a prime example of how technological advancements in weaponry can lead to new challenges in wound ballistics, necessitating improvements in personal protective gear and medical knowledge to manage the resulting injuries effectively.

**Correct Answer:** Kerala 06
