The symbol below describes a nuclide.

{}^{7}_{3}\text{Li}

Which row correctly identifies the proton number ( $Z$ ) and nucleon number ( $A$ )?

Proton number ( $Z$ ) = $3$ , Nucleon number ( $A$ ) = $4$

Proton number ( $Z$ ) = $3$ , Nucleon number ( $A$ ) = $7$

Proton number ( $Z$ ) = $7$ , Nucleon number ( $A$ ) = $3$

Proton number ( $Z$ ) = $7$ , Nucleon number ( $A$ ) = $4$
