A. Molecules are made of atoms, and atoms are made of protons,
neutrons, and electrons.
B. Molecules are made of protons and neutrons, and atoms are
made of electrons and protons.
C. Atoms are made of protons and electrons, and molecules are
made of neutrons and electrons.
D. Atoms are made of molecules, and molecules are made of
protons, neutrons, and electrons.

A

Explanation:

Molecules is made up from and atom is made up with three tiny elements: protons, neutrons, and electron.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
