The choice that has a core composed of ice, dust, and rock is:
**Comets**
1. Comets have a core known as a nucleus, which is composed of ice, dust, and rock. This nucleus is surrounded by a glowing coma and a tail that forms when the comet approaches the Sun and heats up, causing the ice to turn into gas and drag dust particles along.
2. Meteors are rocky or metallic objects that enter Earth's atmosphere and burn up, creating a streak of light. They do not have a core composed of ice, dust, and rock like comets.
3. Stars are massive celestial bodies primarily composed of hydrogen and helium that undergo nuclear fusion to produce energy. They do not have cores made of ice, dust, and rock like comets.
4. Asteroids are rocky objects that orbit the Sun and are primarily composed of rock and metal. They do not typically have cores composed of ice, dust, and rock like comets.
