Check the circled atoms in the attached diagram
Explanation:
The circled options all belongs to the same elements. They are simply isotopes.
Since:
Red ball = protons
Yellow ball = neutron
Blue ball = electron
The protons are positively charged and with the neutrally charged neutrons they both occupy the vicinity of the nucleus of an atom.
Electrons moves round the nucleus in orbits.
Atoms of the same elements have the same number of protons.
The circled options all have two protons.
The atoms only differ in the number of neutrons which signifies that they are merely isotopes.
More descriptively, the atoms are Helium atoms.

Gases take the shape of their container. When you have a large container, the spaces between molecules (particles) can be further apart than if they were close together. In small containers, the particles are forced to be closer together, or compressed.
Think of it like a pep rally in a gym v.s. a classroom. In the gym, everyone has a bit of wiggle room. With the same number of people in a classroom, everyone would need to be packed in there. This can also explain why a smaller pot over boils from steam before a larger one does, even if the amount of water is the same.
answer is B. And chloroplast is only found is plant cells.
