The options that best describes the planetesimals are:

  • Option A. They are the origins of planets.

  • Option B. They formed from gas and dust.

  • Option D. They are believed to have developed in debris disks.

  • It is believed that planets formation occurred through planetesimals. The formation happened from gas, dust particles and debris.

  • By the process of accretion, the discs coalesced and became bigger and solid over time. This bigger mass started attracting other matters towards each other because of gravitational force.

  • This pull resulted in either breaking or creation a bigger mass of pieces known as planetesimals. The collision continued to become bigger and solid planets we know today.

Therefore, options A, B and D are correct.
