Solution

The correct options are
A Atomic number = Number of protons = Number of electrons
B Mass number = Number of protons + Number of neutrons
$∙$ The atomic number gives the number of protons present in an atom. For a neutral atom, it also represents the number of electrons. It is denoted by Z.

$∙$ Mass number represents the sum of the number of protons and neutrons present in the nucleus of an atom. It is denoted by A.
