This is a heterogeneous mixture in which particles settle out unless it is constantly stirred.
A
colloid
B
suspension
C
solution
D
alloy
Explanation: 

Detailed explanation-1: -A suspension is a heterogeneous mixture in which solid particles settle down when left undisturbed.

Detailed explanation-2: -A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution, so gravity is able to pull them down out of the dispersion medium (water).

Detailed explanation-3: -A suspension is a heterogeneous mixture of a finely distributed solid in a liquid. The solid is not dissolved in the liquid, as is the case with a mixture of salt and water.

Detailed explanation-4: -A suspension is a heterogeneous mixture of particles with diameters of about 1 µm (1000 nm) that are distributed throughout a second phase. Common suspensions include paint, blood, and hot chocolate, which are solid particles in a liquid, and aerosol sprays, which are liquid particles in a gas.

Detailed explanation-5: -Suspensions are homogeneous mixtures.
