An atom is represented by

$_z^AX$

here we know that

z = number of protons which gives an idea of positive charge of atom

A = mass number

it is the sum of number of protons and neutrons of an atom which will help us to calculate the mass of the atom

So here mass number A will give us an idea about the mass of atom

so correct answer will be

<em>A) It contains most of the mass.</em>

Explanation:

If i were bungee jumping from a bridge while blowing a hand-held air horn and someone who remains on the bridge will hear a decreased pitch or frequency as the source is moving away from the stationary listener as per the Dooplers effect. Hence, the pitch will progressively lower as the source is moving away from the observer.
