Gravitational attraction exists between all objects in the universe. Which word, if any, should replace "all" in this statement to make the statement true.

any two

Explanation:

Gravitation force or gravitational attraction is a force of pulling or attraction that exist  between any two bodies that have a mass. Each and every body attract each other with the force of gravity due to their masses.

Every object in this universe having mass and distance attracts every other object.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
