B. Object Z, object Y, object X
C. Object X, object Y, object Z.
D. Object Y, object Z, object X

answer: decibel

explanation:

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
