Answer:
A - actinide-series element
Explanation:
If you go to the periodic table, the atomic number is 92. if you look for 92 you will end up in the inner transition metals then if you get more detail it would be in the actinide section.
The most specific classification for the element uranium is option a, it is an actinide series element. It is a radioactive element.
What is uranium?
Uranium is 92nd element in periodic table. This is a f- block element. In periodic table the elements of groups 3-12 is called transition metals. Elements in f block is called inner transition elements.
The inner transition elements contain two classification, lanthanides and actinides. 57th to 71th elements are called lanthanides. 89 to 103 are called actinides.
Thus, uranium belongs to the actinide series of f block elements in the periodic table therefore, option a is correct.

Step1. Write equation out
[CH4 + Cl2 ---> CCl4 + HCl]
C:1; H:4; Cl:2 C:1; H:1; CL:5 /// Cl = 5 since 4Cl + 1Cl
The Carbon element is balanced, but Hydrogen isn't.
So to balance it we will add a coefficient behind HCl, so now
[CH4 + Cl2 ------> CCl4 + 4HCL]
C:1; H:4; Cl:2 C:1; H:4; CL:8 ///// Carbon and hydrogen are balanced, but now Chlorine is not. Now we balance that element by addind a coefficiant behind CL2////
[CH4 + 4Cl2 -----> CCl4 + 4HCl]
C:1; H:4; Cl:8 C:1; H:4; CL:8 ///// So now that we added a 4*Cl2, it equals to Cl:8. So now what most people want to see is if every element is at its lowest balance, so we see if we can any coefficient lower. Just like simplifying if possible.
