Although the rock layer beneath water and humus is known as BEDROCK. So the question should be: Bedrock contains Igneous, Sedimentary or Metamorphic rock. OR The layer beneath water and humus is known as Bedrock.

Class : Class 5
You are very much right. I searched and found out : BEDROCK IS MADE UP OF IGNEOUS, SEDIMENTARY OR METAMORPHIC ROCK and not water and humus.
