A. Meteorites
B. Asteroids
C. Meteors
D. Comets

Hint: We have learned about our solar system which includes sun, asteroids, planets etc. from that information we are going to solve this answer.

Complete step by step answer:
The group of small pieces of rock revolving around the sun between the orbits of mars and Jupiter are called asteroids. The asteroid belt in the solar system is torus, positioned approximately around orbits of the planets Jupiter and Mars, populated by many solid bodies of many sizes but much fewer than the planets, known as asteroids or smaller planets.
Hence, the required answer is asteroids.

So, the correct answer is “Option B”.

Additional Information:
Asteroids: Asteroids, in particular the inner solar system, are minor planets. Often named planetoids are bigger asteroids. The terms were historically used for any astronomical object orbiting the Sun that had no disc in a telescope and no active comet features like a tail were observed. Since small planets were found to be similar to comets in the outside solar system, these have been separated from objects found in the principal asteroid belt. Many of the broken remains of planets, bodies inside the young Sun's nebula, never expanding as large as planets, exist asteroids millions of planets. There are many. In the major asteroid belt located between the orbits of Mars and Jupiter, the vast majority of the identified Asteroids are orbiting or co-orbiting with Jupiter. There are however other orbital families, including near-Earth objects, with large populations.

Note:
Asteroids are residual components of the early solar system. The majority of asteroids are "belt." Asteroids are made of various things. Asteroids lurk in the vicinity of planets.
