Answer 1

Hint: In order to answer the question we have to know about modern periodic table.
In this table elements are classified into four parts as \['s','p','d'\,and\,f - block\] elements according to their electronic configuration and last shell electron.

Complete step by step answer:
Modern periodic table is a display of the elements which are arranged by their atomic number, electronic configuration, chemical and physical properties. It has eighteen columns called groups and seven rows called periods.
Column number 1 and 2 \[( \bot A\,and\,2A)\]are known a s-block elements , \[3\,to\,12\,(III\,B,WB,13 - 18(III\,A,IV\,A,VA,VIA,O)\]as p-block elements and another thirsty elements, stay at the bottom of the periodic table are known as f-block elements and their valence electron goes into \['s','p','d\,'and\,'f'\]orbital’s simultaneously.
General electronic configuration of ‘s block
\[:\,n{s^2}\,(n = 2to7)\,\,[where,\,n = no.\,of\,row]\]
\['p'\,\,block:\,n{s^2}\,n{p^{1 - 6}}(\,n = 2to\,6)\]
\[d\,\,\,block:(n - 1){d^{1 - 10}}\,n{s^{0 - 2}}(\,n = 4to\,7)\]
\[f\,\,\,block:(n - 2){f^{1 - 14}}(n - 1){d^{6 - 1}}\,n{s^{0 - 2}}(\,n = 6to\,7)\]
Here electronic configuration atomic number \[19 - [Ar]4s'\]
\[
  22 - [Ar]4{s^2}\,3{d^2}
  32 - [Ar]4{s^2}\,3{d^{10}}\,4{p^2}
  and\,64 - [ \times e]4{f^7}\,5{d^1}\,6{s^2}
\]

Where Ar and Xe are noble gas with atomic number 18 and 54.
So from the above explanation we clearly understand that atomic number 19- s-block, 22-block, 32-p block and 64-f block element.

The answer is option (B)

Note:
“Periodic table” is a great revolution of science. Still now \[108\] elements have been categorized in similar physical and chemical properties.
From the table we can easily find out the characteristics of any element.
Maximum contain of electrons of \['s','p','d'\,and\,'f'\] orbital (on sub level) is \[2,6,10\,\,and\,14\]orderly.
