1.B. That matter is composed of small indestructible particles.  

2.A. Definite volume and definite shape.

3.B. An element

Explanation:

1.Dalton's atomic theory postulates:

1.It states that matter is composed of atoms that are  indivisible and indestructible.

2.Atoms of an elements are identical .They have same size ,chemical properties and mass.

3.Atoms of one element are different from atoms of another elements.

4.Compounds are composed of atoms of more than one elements.The relative number of atoms of each element in a given compound is always same.

5.Atoms are not created or destroyed during chemical reaction.

B.That matter is composed of small indestructible particles.  

2.Solid:It is that form of substance which have definite shape and definite volume.

Therefore, option A is true.

A. Definite volume and definite shape.

3.An element: it is a simpler substance .It cannot be broken into smaller substance by chemical reactions.

Therefore, option B is true.

B. An element

it's filtration, but this is an assumption so my apologies if i got this
