Hope this will help :)
B.a definite shape,but no definite volume
C.No definite shape,but a definite volume
D.no definite shape and no definite volume
A substance in the solid phase (state) of matter has a definite shape and a definite volume.
Volume is the amount of space taken up by an object, while capacity is the measure of an object's ability to hold a substance, like a solid, a liquid or a gas. Volume is measured in cubic units, while capacity can be measured in almost every other unit, including litres, gallons, pounds, etc.
Matter in the solid-state maintains a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place.
Hence, option A is correct.

B)The nucleus is the dense center of the atom composed of electrons and neutrons. Surrounding the nucleus is an electron cloud composed of protons.
C)The electron cloud is the dense center of the atom composed of electrons. Surrounding the electron cloud is a nucleus composed of protons and neutrons.

D)The electron cloud is the dense center of the atom composed of protons and neutrons. Surrounding the electron cloud is a nucleus composed of electrons.
A is the correct answer I took this tes a few weeks ago.
An atom is structured into a central nucleus containing protons and neutrons, surrounded by an electron cloud that houses the electrons. This is similar to the solar system with the nucleus as the sun and the electrons as the planets revolving around it.
The structure of an atom is organized into two main parts: the nucleus and the electron cloud. The nucleus is the dense central part of the atom and is composed of protons and neutrons. Surrounding the nucleus, in various energy levels or orbits, is a space known as the electron cloud, which contains the electrons.
This structure can be related to the solar system where the nucleus represents the sun and the electrons depict the planets revolving around it. The correct statement that describes the structure of an atom, therefore is option A).
