The element having given electronic configuration is Selenium

Explanation:

Electronic configuration is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom is determined by the atomic number of that atom.

We are given:

An electronic configuration of element:

The number of electrons in the given element = 18 + 2 + 10 + 4 = 34

The element having atomic number '34' is Selenium

Hence, the element having given electronic configuration is Selenium

the answer is option a.
