Hint: The naming ${\text{IUPAC}}$ system gives name to an element according to its atomic number. As the atomic number of an element is given ${\text{119}}$ one can use this data for the correct interpretation of the answer.

1) For the naming of elements the ${\text{IUPAC}}$ system rule is followed. For the elements which have an atomic number more than hundred there are separate rules for the naming of those compounds based on their atomic number.
2) The ${\text{IUPAC}}$ system rules for elements having atomic number more than hundred are as follows:
i) In the atomic number the number one stands as ‘Un’ for each number one.
ii) The numbers nine stands as the ‘en’.
iii) At last after all the numbers the name completes with a suffix ‘ium’
3) Therefore, the atomic number ${\text{119}}$ will show as $1 -$Un, $1 -$Un, $9 -$en and the whole name will be Ununennium.
4) The name Ununennium stands for the symbol ${\text{Uue}}$ for the atomic number ${\text{119}}$ which shows the option C as a correct choice of answer.

So, the correct answer is Option C.

The element Ununennium is also known as eka-francium or element ${\text{119}}$ which is the hypothetical chemical element that is denoted by the symbol ${\text{Uue}}$ in the periodic table. The names Ununennium and ${\text{Uue}}$ are the temporary systematic names in the ${\text{IUPAC}}$ system respectively and these names will be used until the properties of the element are discovered.
