• A. decantation, filtration
• B. sedimentation, decantation
• C. filtration, sedimentation
• D. sedimentation, winnowing

Answer 1

The correct option is B

sedimentation, decantation

Sedimentation is a process in which heavier particles settles down when water is added. And the process of separating the lighter water from the mixture after sedimentation is called decantation.

Hence, the process of settling of rice at the bottom of the beaker is sedimentation and pouring the water out without disturbing the rice is decantation.
