Hi confusedgirl ! Welcome to PF!
Sorry, your picture is very difficult to understand
…
it seems to have an electric charge in it, but I can't work out the rest.
Can you please type out the question, and your answer so far?

The answer is (B) but I don't really understand why.
Based on formula of Young Modulus:
$$x=\frac{FL}{AE}$$
The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A##
I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
