The answer is D. Only student B is correct. Student A is incorrect because static electricity can be detected through the principle of electrostatic induction, which will indicate if there are static electricity on the surface of an object. A device which can detect static electricity is an electroscope. Moreover, for student B, it is correct that the cause for electric current to flow is the uniform flow of free electrons.

Answer:
Explanation:
data is a statement like
data 10,20, 30 , 40 , 50, 60 , 70, 80
\\the numbers represent ages.
For x := 1 to end of data do a[x]:=read(data)
\\ This is a comment. You could do this much easier if you just use three if statements rather than the if then else.
minor:=0;adult:=0;senior:=0;
while a[x] <> 0 do begin
age:= a[x]
if age < 19 then minor:=minor + 1;
If age > 18 then if age < 65 the adult:=adult + 1;
if age > 64 then senior := senior + 1;
end;
I have not declared the variables anywhere. That depends on what language you are using. The key step you want are the three if statements. How you find out what's in them is another matter.
